Small Block Chevy™ Gen3 LS1/LS6, Finned
Valve Covers

P/N 10413

These valve covers fit the center bolt heads used on 3rd Gen Chevrolet® small block engines. Production of these heads began in 1997 with the LS1 used in the Corvette. They also fit LS6. Versions of these heads are also found in Silverado/Sierra, Tahoe/Yukon, Camaro/Firebird, and GTO's.

These valve covers feature raised fins, PCV/breather holes on the intake sides, and two recessed bolts per cover (stock uses four) for a cleaner design. The sand cast aluminum construction provides stiffness so four bolts are not needed to apply pressure evenly to the gasket.

PML supplies gaskets, of our design, with each set.

Coil packs will need to be relocated in order to use these valve covers. Relocation of coil packs is up to the customer.

Valve covers feature internal cast-in baffles. Inside of cover pictured at left.

These valve cover clear Jesel roller rockers.
