Forged in the fires of high performance engines, Fel-Pro performance head gaskets are quite literally created to tame the fiery combustion chambers of up to 1,000 hp engines. Reinforced with KEVLAR® fiber and engineered to give you a perfect seal that can withstand combustion pressures of 1,500 to 3,000 psi, these gaskets are bred for high performance. They have a conformable anti-stick coating—and are constructed with pre-flattened copper or steel rings to make these gaskets easy to install, while also giving them the strength to tame your beastly power plant. Their anti-stick coating ensures easy removal and cleanup on frequent rebuilds, but they also aid in micro-sealing minor surface irregularities. When rebuilding your engine, use the parts you wish were in it to begin with. Put a set of these Fel-Pro performance head gaskets in that engine--not only to help it perform better today, but to make your next engine project that much easier.

Answer This Question


I installed these on my motor and forgot to put in an oil plug that is under the head, should I purchase a new gasket or would it be ok to reuse this one, the head has already been torqued down?

Asked by BOBBY on November 27, 2017


If you have not started it and allowed it to go through "hot and cold cycles" I dont think it will stick and tear when you remove head. Also, I dont think you will compress it any more when you retork it. It should retain the .041 thickness. Not sure you could say that about "all" gaskets but this one will be ok. IMO

Is the set or only one side?

Asked by RANDALL on June 04, 2018


This is one gasket. It fits either side, but there is only one gasket in the package.

well this gasket work on a sbc bored .040 over

Asked by PETER on July 22, 2018


Yes, SBC cylinder bores ranged from 3.500” to 4.125”; these gaskets are sized at 4.166”. So, as long as your cylinders are not bored larger than 4.160” (4.125 + .040 = 4.160) you’ll be fine.
