These 1958-1986 Aluminum Valve Covers Powder Coated Black are standard perimeter mount covers for small block Chevy engines. PML designed these valve covers with the classic CORVETTE script for C1, C2, C3 and 1948-1986 Small Block Chevrolet engines. The CORVETTE script and fins are cast into the cover and raised. On powder coated parts, the powder coat is shaved off the top of the script and fins.
These valve covers do NOT have PCV or Breather Holes.
These covers feature a mid-height design that will clear most roller and/or ratio rockers. There is no correlation between roller rocker ratio and fitment of our valve covers. It is based on the actual physical dimensions of the parts. These valve covers were designed using a stock head and the Jesel Roller rocker system.
