CAUTION: If your engine has non-standard valve train components, such as a high-lift camshaft, roller-tip rocker arm, higher lift ratio rocker arms, stud girdles, etc., there may be insufficient clearance when using the Holley-M/T aluminum valve cover. You must check all internal clearances according to the instructions in the kit.

Overview

Flashback - 1972: Nothing was cooler than sporting around town in a hot rod with a Holley Double Pumper® and M/T® finned aluminum valve covers! Show everyone how cool you are and show up sporting those same parts today! "For the custom engine, M/T offers a superior valve cover of polished aluminum for added cooling. Each die-cast cover is precision manufactured with knock-out plugs for stock PCV (smog Control) and oil fill installations. The M/T polished top cover surface may be used for engraving your name horizontally, next to the deep heat dissipating fins." - Text from 1972 Holley - M/T Performance Parts Catalog. Other historic literature stated that you could expect reduced valve train noise from these cast aluminum M/T covers. The Holley M/T valve covers are available in the new natural cast finish that offers a true nostalgic look on its own, or is ready for custom paint, as well as in the original fully polished, and satin black with machined fins/logo finishes that Holley & M/T helped make popular.

Features:

  • Cast aluminum construction for even gasket sealing and high quality details
  • Precision manufactured with knock-out plugs for stock PCV (smog control) and oil fill installations
  • Deep heat dissipating fins
  • Top cover surface retains vintage style nameplate pad for custom engraving
  • Natural cast finish for a true nostalgic look, or ready for custom paint
