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 seals, and critical surfaces are diamond milled, exceeding original manufacturer specifications. All M96/M97 cylinder heads receive new valve guides and 3-chain 3.4, 3.6, and 3.8 heads receive new intake seats as worn guides and dropped intake seats are a common problem with these engines.


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. Steel or cast iron sleeves are not utilized in our rebuild process. Select engine designations can receive Nickies Lite direct plating process at a substantial discount.


RND Engine feature factory con rods rebuilt using ARP rod bolts, addressing common rod bolts failures.


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 to use undersize bearings that weaken the crankshaft. RND Engines only use Genuine Porsche bearings. All crankshafts are magnaflux crack checked and journals polished.


All engines are fitted with IMS Solution – the industry’s only permanent IMS fix – to prevent future IMS bearing failure.


LN Engineering rigorously inspects all intermediate shafts to verify runout , and the main IMS sprocket is pinned to prevent slippage of the IMS gear.
