I'm pretty sure I'm going to go with a cometic head gasket, but I wanted to get some people opinions on the copper head gaskets. I have a gsr 84mm GE sleeved and O-ringed block AEBS head studs with a b16A head matched to 84. Any thoughts would be appreciated.

 

bump, i'd like to know this to

 

seems to me copper would be weaker, but I don't know

 

I'm asking because i know that a lot of top fuel cars are running copper head gaskets and I have one. The builder who did my engine gave me one, but my tuner who really really knows his stuff is say'n go cometic. I know the copper can seal really well because it's a soft metal and will "crush" around the copper o-rings, but still I've never run a copper head gasket. I just wanted to get some opinions from someone who's tried it or knows someone who has. Looking for some first hand experience but all opinions are more than welcome.
