well i can o ring the block have the cutting setup for my rottler machine i think somone must do it not to far from you i would talk to nitro warrior . i think for your use i would do the head to lock in the head gasket if the deck and head bolt has a weak pattern .i do not know what size your head bolts are your running studs ?

yes pat i have 7/16in ARP studs,even spaced 4 bolts around each cylinder, which isn`t a good pattern for sealing under boost. have you ever heard of any body running a copper gasket with sealer and no o-rings? i was talking to SCE GASKETS they make a titan (brand name) copper gasket that can be used with no o-rings but there sce copper gasket must use o-rings and that is the only one they make for a slantsix. i can get the block o-ringed locally but the cost is as much as buying the tool to do it my self. i don`t know much about the process involved in o-ringing the block or the head and if you have to do both,also the wire size and the groove size, can you help with that so i can get a better price when i tell the machinist exactly what i need.thanks
