I've installed hypermax head gaskets with fire rings along with ARP heads studs. No problems so far, even with a 100 shot of nitrous. The heads did not need to get machined for these gaskets, but hypermax does offer another set of gaskets that require machining to the heads. The special goo is ARP moly lube. ARP wants the studs torqued to 245 ft. lbs. with their moly lube. Are the heads warped ? Is the deck of the block flat? What programmer does the customer have?
