Are 317 Heads Good?

There’s a lot of debate on whether or not 317 heads are good. Some people swear by them, while others think they’re just okay. Personally, I think they’re great!

If you’re looking for a good head for your engine, the 317 heads are a great option. They’re made out of high-quality materials and have been designed to provide excellent performance. Plus, they’re affordable and easy to find.

So, if you’re looking for a good set of heads for your engine, the 317 heads are a great option.

Are 706 Heads Better Than 317 Heads?

There is no easy answer when it comes to deciding whether 706 heads or 317 heads are better for your engine. Both types of heads offer benefits and drawbacks that need to be considered before making a decision. 706 heads have larger intake and exhaust ports than 317 heads, which can improve airflow and power.

However, this also means that 706 heads require more work to install and tune properly. Additionally, the extra port size can cause reliability issues if not done right. 317 heads have smaller ports, which can restrict airflow and power potential compared to 706 heads.

However, they are easier to install and don’t require as much tuning. Additionally, the smaller port size makes them more reliable overall. So, which type of head is best for you?

It depends on your goals and budget. If you’re looking for maximum power potential, then 706 heads may be the way to go. But if you’re looking for an easier installation with fewer headaches, then 317 heads may be a better option.

What Engine Has 317 Heads?

The Chevrolet small-block engine is a series of V8 automobile engines used in normal production by the Chevrolet Division of General Motors between 1955 and 2003, using the same basic engine block.Referred to as a “small block” for its comparative size relative to the physically much larger Chevy big-block engines, the family spanned from 262 cu in (4.3 L) to 400 cu in (6.6 L) displacement. Heads are an important part of any engine, but what exactly are they and what do they do? In short, heads are responsible for sealing the combustion chamber and directing airflow through the engine.

Without good heads, an engine simply wouldn’t run properly or efficiently. So what engine has 317 heads? The Chevrolet small-block engine!

This dependable and powerful engine has been used in everything from everyday cars to high-performance vehicles and everything in between. If you’re looking for an engine that’s both tough and efficient, then look no further than the small-block Chevy!

How Much Do 317 Heads Flow?

How much do 317 heads flow? 317 heads flow about 110 CFM. This is a good amount of airflow for a street engine.

If you are looking for more power, then you may want to consider other heads.

What are the Best 5.3 Heads?

There are a few different types of 5.3 heads, so it really depends on what you’re looking for. If you want the best performance, then aluminum heads are going to be your best bet. However, if you’re looking for something that’s a little more budget-friendly, then cast iron heads may be a better option.

Some of the best performing aluminum heads for the 5.3 include the following: 1) Trick Flow Specialties Twisted Wedge CNC Ported Heads 2) Dart Machinery 327 CNC-Ported Aluminum Heads

3) Brodix BR 3 CNC-Ported Aluminum Heads


What Did 317 Heads Come on

If you’re a Corvette enthusiast, then you know all about the coveted ZR1. This high performance version of the Corvette was first introduced in 1990 and only 317 were made. Why so few?

Because each one was hand-built by Chevrolet’s Special Vehicles group and they took their time to do it right. Each ZR1 came with a 375 horsepower LT5 engine, which was developed jointly with Lotus. It was mated to a six-speed manual transmission and could propel the car from 0-60 mph in 4.4 seconds.

Top speed was an impressive 180 mph. To put that into perspective, the contemporary Ferrari Testarossa – another 90s icon – had a top speed of “just” 170 mph and cost nearly three times as much as the ZR1 at $247,000. So, the ZR1 was not only fast but also a relative bargain!

Unfortunately, production of the ZR1 ceased in 1995 due to emissions regulations changing and Chevrolet not being able to find a way to make it compliant without compromising performance. But those 317 lucky owners have themselves a real collector’s item now!

Best Cam for Lq4 With 317 Heads

A big part of choosing the best cam for your LQ4 with 317 heads is understanding what each type of cam offers. There are three main types of cams: street, strip and off-road. Each has their own unique characteristics that make them better or worse for different applications.

For example, a street cam is going to be much more mild than a race cam. It will idle smoothly, have good low end power and not be too loud. However, it won’t make as much top end power as a race cam.

A strip cam is going to be in between the two. It will idle a little rougher than a street cam and be louder, but it will make more power than a street cam. Lastly, an off-road cam is going to be the most aggressive.

It will idle very rough, be extremely loud and make lots of power. However, it may not run well on the street if you don’t have other modifications like headers and exhaust to go along with it.

So which one is best for your LQ4 with 317 heads?

That depends on how you plan on using the engine. If you want something that will perform well on the street and still have good power, then a street cam is probably your best bet. If you want something that performs well at the dragstrip or track, then a strip or off-road cam would be more appropriate.

Just keep in mind that an off-road cam may not work well on the street unless you have other mods to support it.

Are 317 Heads Cathedral Port

If you’re a diehard GM performance enthusiast, then the chances are good that you’re very familiar with the Chevrolet LS engine. This powerful and efficient V8 has become one of the most popular engines in recent years, thanks to its versatility and relatively low cost of ownership. One of the most popular variations of the LS engine is the 317 cid (5.3L) version, which features cathedral port cylinder heads.

In this article, we’re going to take a close look at the 317 heads and see what makes them so special. We’ll also touch on some of the key differences between cathedral and rectangular port heads, so that you can make an informed decision about which type is right for your own performance application. So, what exactly are 317 heads?

As we mentioned earlier, they are simply LS cylinder heads that have been machined for use with a 5.3L displacement engine block. The “cathedral port” designation comes from the unique shape of their intake ports, which are taller and narrower than those found on other LS head castings such as the L92/93 Heads . This Cathedral port design was first introduced on the 1997 model year 454 SS truck engines and quickly made its way into other high-performance applications such as drag racing and circle track racing.

One of the benefits of using cathedral port heads is that they offer excellent airflow potential due to their large intake ports. This increased airflow can translate into more power, especially at higher engine speeds where volumetric efficiency becomes increasingly important. In addition, Cathedral port heads tend to produce more torque than their rectangular port counterparts due to their larger exhaust ports – making them ideal for street/strip applications where low-end grunt is key.

Of course, there are tradeoffs to consider when choosing between cathedral and rectangular port heads. Because of their larger size, cathedral port heads can be more difficult to package in certain engine bay configurations – particularly if space is tight around the valve covers. In addition, Cathedralport heads require longer pushrods than rectangular port designs due to their taller intake ports (pushrod length is determined by distance between rocker arms and valves).

Finally, because they flow more air than rectangular ported designs, cathedralportheads can be more prone to overheating in hot weather conditions or during extended periods of hard driving – making them less ideal for daily driver applications where reliability is paramount .

Ported 317 Heads

Ported 317 heads are an excellent choice for those looking to improve the performance of their car or truck. They offer increased airflow and combustion efficiency, resulting in more power and better fuel economy. They’re also relatively easy to install, so they’re a great option for do-it-yourselfers.


If you’re a diehard Ford fan, then the answer is probably yes. The 317 heads were originally designed for the 1963 Fairlane and were used on a variety of performance engines throughout the 1960s. They’re still popular today because they offer good airflow and can be had for relatively cheap.
