Ok i did some research but didn't find enough info so here is my question :

B18c block overbored to 84mm what head gasket do i use ?

The B18c one is 82mm if im not mistaking. Since the B20 is 84mm i was thinking of using that head gasket but not sure about it ...

The other thing i read up on is that some people use oem 82mm and cut them out to the desired bore... if that's a good method how do you guys cut it out so its perfect ?

I know there is COMETIC head gasket but my question is does a b20 head gasket better if it fits on a b18c block ? this i for a turbo set up aroud 350-400 whp

thanks

Golden Eagle makes overbored OEM headgaskets. I wouldn't use the B20 one since the rivets can interfere with the head and one of them usually has to be removed to use a non-VTEC headgasket with a VTEC head. You could use a Cometic gasket, but the OEM gaskets are great, and a lot of people(myself included) swear by them.

GE or Cometic
