whats the bore size on a OEM headgasket? I think its 82mm if so then its fine because my build will have 81.5mm pistons so i don't want a 81mm headgasket.

found it myself its 81.75mm should have looked deeper and just used google

 

Really guy??? What headgasket are we talking about?

 

do you read?

 

um yeah, should we guess what head gasket,block, and head your using?
chill out. we cant read what you didn't type.

 

okay a b-series head gasket i figured since the only motor around 81mm was the b-series people might catch up on that but i guess not

 

b18 or b20?

 

so buy a damn gasket that matches your bore size or .5 bigger. whats the issue here?

 

really? a b20 has a 84mm so CLEARLY it won't ever use a 81 or 81.5mm bore headgasket

and i'd prefer a OEM head gasket i'd rather not buy a aftermarket one

 

golden eagle is oem bro.
