BB Chevy oval port,Complete  110cc Performer 454-O cylinder heads have the same outstanding features as the Performer RPM heads but with an exhaust crossover passage for a 50-state emissions legal status. Match these powerful heads with our Performer manifold, Performer-Plus cam and an Edelbrock square-bore or spread-bore carburetor for a Power Package that’s capable of over 470 ft/lbs. of torque at 3500 rpm.

Tech Tip: To gain more spark plug clearance, Edelbrock recommends using Champion RC Series plugs such as the RC12YC . They are 0.230'' shorter than a conventional spark plug and have a 5/8'' hex for easier access.

Performer 454 Cylinder Heads
These oval port heads will support over 540 hp with 9.5:1 compression with the right combination! Unique oval intake port shape produces flow similar to rectangular ports, but the smaller port size provides excellent seat-of-the-pant performance and crisp throttle response. Semi-open chamber design maximizes efficiency with streetable compression ratios. The smaller-than-stock 11/32'' valve stems provide excellent flow and lighter valve weight.
