When it comes to the amount of power your engine can produce, the cylinder heads are a major component. Cylinder heads flows fuel/air in and exhaust gases out, so needless to say, it's important in building horsepower and torque. As with most engine components, bigger isn't always better and selecting the right heads is crucial to making big time horsepower. Trust the pros at Speedway Motors to not only help you select the right cylinder heads for your application, but also to get the best prices around.
