Small Block Chrysler Performer RPM 65cc Aluminum Cylinder Heads

1968-1973 Chrysler Small Block 340ci
Port Volume: 171cc/77cc
65cc Combustion Chambers

Bare, Sold Individually

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.
