These 1958-1982 Aluminum Valve Covers Polished Aluminum with Corvette Script 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 1984-1986 Corvette 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.
This set does 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.
