These new Mark IV V8 (396-427-454-502) tall valve covers from PML will be, if you’re running a set of roller rockers on that big block engine.
That’s because they have an extra 3/8-inch clearance for those rockers, compared to stock and reproduction 396-427-454-502 big block valve covers, plus they come with breather holes and cast-in baffling. They also feature the classic finned-with-“Corvette”-script styling, and you can choose from three finishes: As-cast, polished or powder-coated. PML Inc. 310-671-4345 www.yourcovers.com
