Description

The Choate Performance Engineering CEPLMMWHR is an upgraded, remanufactured 6.6 Duramax LMM Workhorse Cylinder Head designed for diesel engines. It features a resurfaced cylinder head that meets or exceeds OEM specifications for Ra to maximize sealing performance, new valve stem seals, new valve guides, reground valves, and 3-angle cut seats for optimized flow. The heads are machined with O-rings to eliminate common factory head gasket issues, utilizing a USA-made stainless steel wire for superior combustion pressure sealing.
