Are All LS Headers The Same?

Are ls1 and ls2 headers the same?

The headers are the same..

Are headers louder than manifolds?

Another disadvantage of headers is that, due to their thinner walls, they do not absorb as much sound as cast iron exhaust manifolds, making them louder (although some may see this an advantage).

How good are LS 706 heads?

706 heads are plentiful and easy to find. 706 heads have smaller chambers, so you don’t lose compression. 706 heads are slightly superior to 862 heads due to how they are manufactured. 706 heads flow great and, overall, are superior to 317 heads for many builds.

Are engine heads interchangeable?

Stamped on the intake side, they are numbers. Some V-6 and V-8 engines have cylinder heads that are interchangeable for the left and right sides. … Identify your required cylinder head using your cars vin number. Some cylinder heads can be identified by using parts from the vin number.

How much horsepower do headers add to a 350?

The length of the primary tubing determines the effective rpm range, but headers can be worth 15-20 hp on the right application. Run on our restrictive two-barrel 350, the headers improved the power output to 248 hp and 365 lb-ft of torque, with consistent gains through the rev range.

Are 317 LS heads any good?

317 are the same as the 243/799 head but with a larger combustion chamber as you have noted. So it flows fine. But for a street car, I’d want to bump the compression. If you are running boost… the 317 untouched would be a good head.

Are LS heads reversible?

They are reversible. They’re all the same… Just swap your temp sender to the other side. You’ll also need to make sure the plugs in the ends of the heads are on the front.

Are all LS exhaust ports the same?

All LS engines have the same exhaust port spacing and can use the same headers.

Are 5.3 and 6.0 headers the same?

the 4.8 5.3 fit the 6.0L any other parts like that interchange? They will fit fine. Bolt pattern on the heads is the same. Motors internally/externally are pretty much identical.

What are the different types of headers?

Header StylesWalk through a rod run or flip through a header catalog and it’s obvious that there are numerous styles of headers, which fall into these general categories: full-length headers, shorties, lakester style, and tri-Y.

Which LS heads are the best?

The LS6 was designed specifically by GM to surpass the LS1 as the best performance head, and it did such a good job that the “243” casting was recycled on the LS2. Aside from the LQ9, which is a copy of the LS6, these are the best performing of the OEM cathedral ports.

Are LS heads side specific?

Most OHC engines the cylinder heads are side specific. On properly engineered engines like the LS1, they are identical. With two driver’s heads, the car will want to turn left. That’s what they do in Nascar because they are always turning left.

Will ls3 headers fit ls2?

The LS1, LS6, LS2, LS3 heads all have the same mounting points for headers on the heads/exhaust ports.

Which is better long tube or shorty headers?

Compared to your stock exhaust manifold, shorty headers still have a much longer tube. … Unequal length headers offer a deeper rumbling sound and a little more low-end torque, but equal length headers offer greater performance gains consistently.

Are all SBC heads interchangeable?

All SBC gen I and Gen II heads will bolt onto the block. The LT1 and 4 heads are set up for reverse coolant flow(i.e. the water goes from the heads then through the block) so those aren’t what you want to use. The center bolt non-vortec heads(87-96) use a slightly different intake manifold.
