Similar to the crossflow heads that were available back in the 1960's, but now made of lightweight aluminum alloy rather than Cast Iron and the design has been dramatically improved. 

Our head was designed using gas-flow porting technology, that had yielded amazing performance results, all while allowing you to use your original exhaust or performance header!  The Carb mounting flanges accept Weber DCOE or equivalent carbs.  Mounting studs and nuts are included.

The designed has be so refined that over-sizing the valves is not necessary.  The improvement in air flow through the combustion chamber has made oversized valves counterproductive.

This head was designed for simple installation, and will even fit the cramped Mini engine compartment with the two Weber carbs installed.  No cutting or "massaging" of the engine compartment.
