Flashback - 1972: Nothing was cooler than cruising around town in a hot rod with a Holley Double Pumper® and M/T® finned aluminum valve covers! Embrace the nostalgia and show up sporting a new and improved version of 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 valve covers. In an attempt to expand the range of the M/T valve cover line for Big Block Chevy engines, this new and improved Tall version offers increased valve train clearance for high-lift rockers and some applications of stud girdles. We've brought them back in the original polished and satin black with machined fins/logo finishes that Holley & M/T helped make popular, as well as a natural cast finish that offers a true nostalgic look on its own, or is ready for custom paint! Order a set today and get back your hot rodding groove!

Features:

  • Cast aluminum construction for even gasket sealing and high quality details
  • Tall M/T valve covers for BBC applications allow for generous aftermarket rocker and some applications of stud girdle clearance
  • Precision manufactured with knock-out plugs for stock PCV (smog control) and oil fill installations
  • Includes baffle plates (with mounting screws) and a period correct twist-on oil fill cap
  • Deep heat dissipating fins
  • Top cover surface retains vintage style nameplate pad for custom engraving
  • Available in three classic finishes: natural cast, polished, and satin black with machined fins/logo
