Clevite P-Series Main Bearings
Clevite P-Series main bearings are the oldest members of the Clevite 77 bearing family and are intended for high-revving engines. To compensate for the high-load factors and distortion in these engines, these bearings have higher eccentricity and a high crush factor. P-Series bearings are constructed of tri-metal cast copper lead. They have a steel back for support, a cast copper lead lining to withstand the loads of engine operation, and an electroplated babbit overlay on the running surface to provide searing surface qualities. In addition, the oil grooves on most applications extend all the way around both halves for better oiling. Clevite P-Series main bearings are an ideal design, producing a degree of conformability, embedability, slipperiness, and fatigue resistance, not found in original equipment and competitive bimetal bearings.

Cometic MLS Head Gaskets
Cometic MLS head gaskets are constructed from multiple layers of stainless steel for additional strength over traditional gaskets. They contain load-controlled embossments that help conform load distribution across the sealing area, and where applicable, valve pocketing to avoid chamber intrusion. This creates an exceptional seal by requiring less clamp load and resulting in less bore distortion. The stainless-steel outer layers utilize a rubber-binder coating that features high-temperature and chemical-resistant polymers. These gaskets are available for most cylinder heads. As with all Cometic MLS head gaskets, no sealants or re-torque is required when properly installed on prepared surfaces. Get the engine performance you want with an assist from the Cometic MLS head gaskets best suited for your application.
