Performer RPM Aluminum Cylinder Heads - Oval Port

Big Block Chevy 396-502ci
Valve Springs for Hydraulic Flat Tappet
Port Volume: 290cc/110cc
Valve Size: 2.19"/1.88"
110cc Combustion Chambers
Max Lift: .700"
Assembled, Sold Individually
These oval port heads will support over 540 hp with 9.5:1 compression when used as part of the Edelbrock Total Power Package.
Unique oval intake port shape produces flow similar to rectangular ports, but the smaller port size provides excellent seat-of-the-pants performance and crisp throttle response.
Semi-open chamber design maximizes efficiency with streetable compression ratios.

Smaller-than-stock 11/32' valve stems promote excellent flow and lighter valve weight.

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.
