Valve Cover Chevy SB Tall Center Bolt Ball-Milled Polished

Available tall style only with a 1-1/4 diameter breather hole positioned between the rockers to reduce oil splash. Valve covers are produced from a high-grade aluminum that is polished to Billet Specialties standards and each design is CNC machined in the USA. For the best seal, Billet Specialties recommends the use of a cork gasket with all of the valve covers we sell.
