First, Cometic makes some good gaskets. The FelPro 1008 gaskets
@GTX JOHN spoke about are also good.
That said, lets address something. You DO have quench. It might not be "optimal" but you do have it. Also, since it's not optimal, that COULD be a factor in your blown head gaskets. Too much quench can allow detonation to sometimes occur and that can pop head gaskets in short order.
