The Cometic Ford 302/351 SVO SB 4.030 inch Bore .027 inch MLS Head Gasket - C5478-027 is a precision-engineered head gasket with a 4.030" bore and .030" compressed thickness.

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