Performer RPM Aluminum Cylinder Heads - Oval Port
  • Big Block Chevy 396-502ci
  • Port Volume: 290cc/110cc
  • 110cc Combustion Chambers
  • Bare, Sold Individually

    Designed for big-block Chevy 396-502 c.i.d. engines, these oval port heads will support over 540 horsepower with 9.5:1 compression when used as part of the Performer RPM Power Package. A totally unique intake port design yields flow numbers traditionally associated with high performance rectangular port heads, but with the smaller runner size and velocity of an oval port for excellent seat-of-the-pants performance and crisp throttle response. The semi-open chamber design maximizes combustion efficiency with streetable compression ratios. The stainless steel 2.19' intake and 1.88' exhaust valves have smaller-than-stock 11/32' valve stems to promote excellent flow and lighter valve weight. The deck surface and water jackets were specially designed to work with all big-block Chevrolet engine blocks. Heads include top-quality ARP rocker studs, bronze guides and hardened, ductile iron valve seats.

    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.
