Designed for non-emissions 302, 327, 350 and 400 c.i.d. engines up to 1986, these heads Designed for non-emissions 302, 327, 350 and 400 c.i.d. engines up to 1986, these heads made 420 horsepower with the Performer RPM Power Package for small-block Chevys. Hardened pushrods are required.
Installation Notes: When using stock rockers on SB-Chevy Performer & Performer RPM heads, .100' longer than stock pushrods are required. Due to valve-to-cylinder bore interference, SB-Chevy heads may not be used on engines with less than 4' bore (262, 265, 283, 305, 307 c.i.d.) except with camshafts having less than .450' valve lift.
Tech Tip: To gain more spark plug clearance, Edelbrock recommends using Champion RC Series plugs such as the RC12YC (P/N 192-49776). They are 0.230' shorter than a conventional spark plug and have a 5/8' hex for easier access.Combustion Chamber Volume: 70cc Intake Runner Volume: 195cc Exhaust Runner Volume: 65cc Intake Valve Diameter: 2.02' Exhaust Valve Diameter: 1.60' Valve Stem Diameter: 11/32' Valve Guides: Manganese Bronze Deck Thickness: 9/16' Valve Spring Diameter: 1.46' Valve Spring Maximum Lift: 0.575' Rocker Stud: 3/8' Guideplate: Hardened Steel Pushrod Diameter: 5/16' Valve Angle: 23° Exhaust Port Location: Stock Spark Plug Fitment: 14mm x 3/4' Reach,
