Edelbrock 60769 - Edelbrock Small Block Chrysler Performer RPM Cylinder Heads Details

Chrysler Performer RPM Aluminum Cylinder Heads

Other outstanding features include phosphor-bronze valve guides, interlocking, ductile iron valve seats, and premium one-piece, high-flow stainless steel intake and exhaust valves. Heat-treated and machined steel retainers and valve locks along with heavy duty valve springs are good for .575'' lift cams. 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.

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.
