The Cometic Pontiac V8 350 3.950in Bore .027in MLS Head Gasket - C5710-027 is a precision-engineered head gasket with a 3.950" bore and .950" compressed thickness.

The Cometic Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short.
