why cant you oring the block? if you did this and cut the receiver grove in the head you will blow the rods out the bottom before you move the head gasket did you call cometic

pat i called auto machine shops in this area and none of them have the tools to o-ring blocks and to buy the tool from isky is $500can. i need the smaller tool for 3.48in bore, the local industial machine shop said they can do it on a milling machine and it $70hrs (6hrs just for the block) i never asked about the head i didn`t know about needing a reciever groove.so i need to do some more testing with what worked this summer, if it doesn`t hold up long and starts blowing gaskets again i will have to try to get it o-ringed some way.

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
