Fel-Pro PermaDryPlus Valve Cover Gaskets VS50504R

Fel-Pro's PermaDryPlus valve cover gaskets feature precision edge-molded silicone rubber, which resists high heat and delivers reliable sealing on irregular surfaces. This silicone rubber is wrapped around a rigid carrier that adds strength to the gasket to resist being sucked in under high vacuum or blown out when under pressure. At the same time, it also prevents over-tightening of the mounting bolts. Note, however, that these gaskets are not intended for race applications.
