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 M/T covers. Get a set today and get back your hot rodding groove!
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.
