Dart blocks and cylinder heads provide an exceptional value at an affordable price. Precision machining and quality control measures mean you get optimum out of the box performance. A \"bargain\" component can wind up costing far more after the machining which will be required to make it usable. Our cylinder heads offer considerable added value as well.

Fully assembled or bare heads can be ordered with combustion chambers matched to your bore size.
