o ring headgasket vs metal

[TsiDan]

so my local machine shop is almost done building my new head and we were going over the type of headgasket i should use. the guy who did the work suggested that i "o ring" the head and use an oem cosmetic headgasket rather than a metal one. im going for a pretty high horsepower build since im forged and now have a built head. which headgasket would be the safer route? thanks.

An O ring will be better and much more expensive but for your build a metal one will be more than enough!

+1 metal should be good enough

If the machine shop didn't put a mirror smooth finish on your block and head, then take their advise and go o-ring.

well both the head and block were machined smooth.. but the block had a different head on it for the past 300 or so miles.. until my gasket blew and warped it..

the machinist said he would o ring the head for 150. and throw in his spare oem gasket for 40. hows that for pricing?

Might want to check out the first copper head gasket on this page before anyone does any more machining.
