These cylinder heads are designed for outstanding performance gains in 1962-1979 389-455 c.i.d. Pontiac engines. They are patterned after the 1969-70 Ram Air IV Pontiac cylinder head with the 72cc combustion chamber for higher compression engines.
Tech Tip: These heads require Ram Air IV (round port) style exhaust manifolds or headers and Edelbrock head bolt kit 350-8549.
To gain more spark plug clearance, Edelbrock recommends using Champion RC Series plugs, such as the RC12YC. They are 0.230' shorter than conventional spark plugs and have a 5/8' hex for easier access.Combustion Chamber Volume: 72cc Intake Runner Volume: 215cc Exhaust Runner Volume: 175cc Intake Valve Diameter: 2.11' Exhaust Valve Diameter: 1.66' Valve Stem Diameter: 11/32' Valve Guides: Manganese Bronze Deck Thickness: 5/8' Valve Spring Diameter: 1.46' Valve Spring Maximum Lift: 0.575' Rocker Stud: 7/16' Guideplate: Hardened Steel Pushrod Diameter: 5/16' Valve Angle: 14° Exhaust Port Location: Stock Ram Air IV Spark Plug Fitment: 14mm x 3/4' Reach,
