Review on 🔧 Quality-Engineered Fel-Pro-KS2666 Gasket Set for Optimal Performance by John Koch

I've been building small blocks for Chevy for over 30 years, I've only used Felpro gaskets for as long as I can remember and never gotten a bad one. I had an assistant who once made the cylinder head gaskets himself and they were leaking within a week when disassembling, he forgot to tighten the cylinder head bolts as specified, they were too loose and all with different torques. This is the only time I've had a bug.
