Performer RPM 454-O Cylinder Heads - Single - Complete BB Chevy Oval Port, 110cc chambers, great torque and horsepower up to 6500 rpm
AFFORDABLE QUALITY, COMPLETE EACH
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 maximizes efficiency with streetable compression ratios.
- Smaller-than-stock 11/32" valve stems promote excellent flow and lighter valve weight.
