AIRCOOLED AND WATERCOOLED PORSCHE CYLINDER HEAD REBUILD SERVICE

RND cylinder heads benefit from years of experience with thousands of Porsche heads rebuilt by our specialists to date. 100% of components are tested, reconditioned, or replaced and feature multi-angle Serdi valve job, Viton valve stem seals, and critical surfaces are diamond milled, exceeding original manufacturer specifications. All components are inspected and replaced if worn. M96/M97 heads are always pressure tested and all cylinder heads are vacuum tested after final assembly as part of our standard quality control checks.
