Cometic H3451SP1051S MLS Head Gasket Bore Thick - 3.451in 1.05mm

The Cometic H3451SP1051S is a high-performance Multi-Layer Steel (MLS) head gasket engineered for demanding street and competition engine builds. Featuring a 3.451-inch bore and 1.05mm compressed thickness, this gasket delivers exceptional sealing performance under extreme cylinder pressures and temperatures.

Cometic's MLS head gaskets are constructed from multiple embossed stainless steel layers that conform to even slightly irregular head and block surfaces, providing a superior seal compared to traditional composite gaskets. Each layer works in concert to maintain consistent clamping load and resist blowout under high-boost or high-compression conditions.
