Designed for high-performance street, strip, and marine, these heads have the same features as #350-6076 and #350-6077 but the chambers have been machined .060" for clearance with early high compression engines. The special valvetrain in the 1970 340 T/A is not compatible with these cylinder heads.
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 conventional spark plugs and have a 5/8' hex for easier access.Combustion Chamber Volume: 65cc Intake Runner Volume: 171cc Exhaust Runner Volume: 77cc Intake Valve Diameter: 2.02' Exhaust Valve Diameter: 1.60' 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: N/A Guideplate: Hardened Steel Pushrod Diameter: 5/16' Valve Angle: 18° Exhaust Port Location: Stock Spark Plug Fitment: 14mm x 3/4' Reach,
