hate to tell ya the bad news bud, but running the arp head studs with a cometic head gasket dont work...
one of the head studs is used as an oil feed to transfer oil from one side of the block to the other.
with a cometic head gasket, it doesnt have a crush washer or anything to seal around the head stud, therefore it pisses out oil from the side of the head.
i found out the hard way and the expensive way unfortunately.
ended up having to run a tomei head gasket which will set ya back about $400 bucks.
worth every penny so far (fingers crossed).
good luck
