blown 2 head gaskets

Um... If the block is O-ringed, you have to run the O-ring type head gaskets. You are not doing anything IMO that requires the O-rings if the head and block were machined properly, and you're using at minimum ARP head bolts if not studs. But, you can't run the standard head gaskets with the block O-ringed and expect them to work. If you need to stick with the .045" thick deals use these:

Again, your block and heads must be flat. VERY flat.
