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.

    Using proprietary Speed Flow technology, Dart has developed more efficient port designs with improved velocity and flow capabilities. The combustion chambers and ports have been redesigned for greater breathing characteristics and more controllable combustion. Casting walls are cleaner and more consistent, resulting in better control over flow and heat.

    • Standard 23 degree valve angle
    • Standard port location and intake bolt pattern fit most manifolds
    • Pushrod holes enlarged for clearance with high ratio rocker arms
    • Heart shaped chambers improve combustion efficiency
    • Multi-angle intake seats and radiused exhaust seats dramatically increase airflow
    • Hardened exhaust seats compatible with unleaded gasoline
    • Manganese bronze intake valve guides and phosphorous bronze exhaust valve guides extend cylinder head life
    • Spark plug holes are machined for tapered seat 5/8" hex "peanut" spark plugs
    • Dual bolt pattern accepts flange mount and center bolt valve covers
