I started with Felpro's and they blew out and leaked. I switched to the Percy high temp carbon gaskets and never had a problem after that. Make sure you don't have a leak somewhere else like the AIR fittings or the y-pipe connections though. The Felpro 1406 is really for ported heads and has very little material on the edges so be careful if you switch to them. These are the Felpro 1406.
