Performer RPM heads are perfect for street performance, daily drivers, street rods and muscle cars where seat-of-the-pants performance is needed. These heads give great torque and horsepower up to 6500 rpm.
These oval port heads will support over 540 hp with 9.5:1 compression when used as part of the 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 maximises efficiency with streetable compression ratios.
Smaller-than-stock 11/32" valve stems promote excellent flow and lighter valve weight.
