Fitment:Designed for 212cc Hemi Predator Engines Only. Precision CNC Machining：Manufactured using advanced CNC machining technology to achieve precise dimensions and consistent structure.Features a bright plated coating with self-lubricating characteristics that helps reduce friction between moving components. The coating also provides excellent corrosion resistance, high hardness, and a polished appearance that enhances the engine’s visual appeal. Heightened internal space：The interior of this modification is taller and deeper to accommodate high-lift camshafts, dual springs (such as 26lb/32lb) and roller rocker arms to prevent the valve train from hitting the valve cover when operating. Comes with pulse connector：1/4" NPT threaded hole is reserved at the top and comes standard with a brass connector, which can be used to connect the oil collection tank to release the crankcase pressure, eliminating the trouble of drilling and tapping by yourself. The connector on the valve cover allows the gas with oil mist to be discharged to prevent excessive pressure from damaging the crankshaft oil seal. Eliminate oil leakage: The thickened design of the mounting surface, combined with high-quality gaskets, ensures extremely uniform stress and solves oil leakage and oil leakage caused by uneven torque deformation.
