Performer RPM Small Block Aluminum Straight Plug Cylinder Heads
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.
