SBC MLS Head Gasket 305 RaceSaver Sprint

The SBC MLS Head Gasket 305 RaceSaver Sprint by COMETIC GASKETS is engineered for serious small-block Chevrolet sprint car and race engine builders who demand reliability under extreme cylinder pressure and temperature cycling. This multi-layer steel (MLS) gasket is the standard choice for 305 cubic inch RaceSaver sprint engines competing at the highest levels of regional and national sprint car racing. Whether you're rebuilding a tired engine for competition or freshening a proven power plant, this gasket delivers the consistency and longevity that separates winning teams from the field.

MLS head gasket technology uses stainless steel layers bonded to a composite core, creating a superior sealing surface that resists blow-by and maintains compression across multiple heat cycles that would destroy conventional composite gaskets. The multi-layer construction allows the gasket to conform precisely to the cylinder head and block deck surfaces, accommodating the microscopic variances inherent in sprint car engine machining while preventing coolant and oil weeping at critical junction points. The 0.040-inch compressed thickness specified in this gasket is calibrated for the exact combustion chamber volume and quench clearance requirements of RaceSaver-legal 305 strokers, ensuring optimal ignition timing and cylinder pressure stability throughout the RPM range.

Sprint car competitors using 305 RaceSaver engines benefit most from this gasket's proven durability in high-RPM, high-load environments where head lift and thermal stress are constant threats. Installation requires careful deck surface preparation, proper head bolt torque sequencing, and compliance with COMETIC's documented installation protocols to achieve the full design margin of safety. This gasket is compatible with standard small-block Chevrolet cylinder head bolt patterns and works seamlessly with both factory and aftermarket cast-iron or aluminum heads commonly found in sprint car competition applications.
