I think bossbird would expose head gasket issues on ra5 heads by now. Nitro seems to find the weak link. And again if it was head bolt related why doesn't anyone ever blow out the end cylinders? Why is it that the gasket fails between the center cylinders right where the exhaust valves are everytime and no place else? Why when adding better cooling to that area do the head gaskets last twice as long? To me that all points to heat not a head bolt issue.
