    For everything else you can do to amp up your engine, it allow comes down to combustion – and in this sense, the cylinder block is the heart of the engine. A good cylinder head and valvetrain are essential for maximizing the effectiveness of the combustion chamber and pushing air, fuel and exhaust where they need to go. Our automotive cylinder heads and valvetrain components maximize flow for performance so incredible, this chamber of secrets will seem almost wizardly.

    We offer auto cylinder heads and cylinder rebuilds that are precision-machined for maximum efficiency and usable power. Cosworth big valve cylinder heads and Tomei heads come complete with ported runners, performance valve jobs and upgraded camshafts. For Mitubishi Evo owners, MAP offers five stages of in-house cylinder head preparation, ranging from basic valve jobs and cleaning to aggressive porting and polishing for serious racers. We also offer a cylinder overbore option with multiple choices for valves, seals, guides and springs.

    If you’re looking to do your own rebuild or maintenance, our valvetrain parts run the gamut for vehicles and engines of all kinds. MAP high performance valves use an undercut stem that reduces weight for improved air/fuel flow and RPM limits. Strong seals are vital for keeping fluids and gasses contained, and Cometic head gaskets use three layers of stainless steel for long lasting protection. In our inventory, you can find camshafts, aluminum valve covers, intake valve guides, beehive valve springs and anything else you can think of for overhauling your valvetrain.
