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 with racing guides, Viton seals, and critical surfaces are diamond milled, exceeding original manufacturer specifications.
RND Engines are never just re-ringed or have single cylinder repairs as most engines are not suitable for rebuilding without re-sleeving. RND Engines exclusively use LN Engineering’s proven aluminum NSC-plated sleeves which exceed the strength and longevity of the original cylinders.
RND Engines use only NEW or OE used cranks from engines that have not suffered any failure and meet strict RND standards. RND cranks are not cut, welded, or repaired to fix damage or to use undersize bearings that weaken the crankshaft. RND Engines only use Genuine Porsche bearings.
