Im trying to figure out what exhaust gasket to use for my b17a1. I used a 99 civic si intake manifold gasket and it fit fine, but i tried the 99 civic si exhuast gasket and it was way off, the bolt holes were off by at least 1/8"+.

So what exhuast gasket will work (other than b17a1)?

Also, can I use b16 cams in a b17 head? I believe the b17 head code is PR3.

 

It appears that Honda gave you an incorrect gasket as the Si gasket will indeed work just fine.

 

the b17a1 gasket is listed as part # 18115-P30-013
the 99 Si gasket is listed as part# 18115-P72-003

so it looks like they are not the same. go to any honda/acura dealership and ask for the first part number and see if it cross references with any of their parts.

or just order one from http://www.acuraparts247.com

the intake manifold gaskets part #'s match up for both engines so thats why it worked. thats weird the exhaust mani gasket is different.

 

good info

i actually just asked for the 99si gasket from advanced cause i assumed they were the same. Goin to get teh right one now

Weirdness!
