Any differences in bolt pattern on k20, k20a2, and k20a3 exhaust manifold??

[nl22]

Well I'm testing out some ideas and been researching all over the internet, is there a difference in bolt pattern on the k20a, k20a2, and k20a3?? Or are they all the same meaning a exhaust manifold meant for any of the engines can fit on any of the heads?

No. They all bolt right up. Only issue you can have is sway bar clearance.

I have no problem helping out, but I see this time and time again with newer people.. But, SEARCH! Nothing on here is hard to find. Everything is labeled specifically.

The only thing different between the a3 vs a2/z1 race header is that the a2/z1 is 2.5" longer. So you would need a type-s midpipe or custom midpipe.
