EQ Performance Cylinder Heads: More Bang for the Buck!
Engine enthusiasts agree: EQ makes the best-performing, best-priced cylinder heads for maximum power with minimum effort. Cast at the factory into a ‘hand ported’ shape, they’re ready to install right out of the box, requiring no additional machining, porting or polishing. Just install the valve train, bolt on – and hold on!
Our 23 degree performance cylinder heads feature Flow-Cast Technology, the latest advancement in air-flow design. In fact, they were voted Best of Tech by Popular Hot Rodding. Vehicles running with EQ performance heads out-gun the competition on race tracks across the nation.
