Gonna pull the head off of the Black Bitch and with the new modifications (9-1 forged pistons) should I do OEM or an aftermarket head gasket? We are gonna put some ARP's in there as well....Anything else????

all I've ever heard is that the factory mitsu metal head gasket is the best.

The head is coming off and if it is out of spec it will be milled...So I am also hearing that the Mitsu metal gasket is a good choice.

OEM Mitsu stuff is GREAT! The headgaskets is one of the few things that they did very well over in Japan. I know though that, if you're worried, you can get an HKS headgasket I believe.
