Small Block Chrysler Performer RPM 63cc Aluminum Cylinder Heads
Designed for outstanding performance in non-emission 1967-1991 Chrysler 318-340-360 engines. For compatibility with aftermarket parts, these heads use the stock location for intake and exhaust bolt holes and flanges, spark plugs, and valve cover rails. 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.
