UPDATE!!! After a quick research ive learned that i have the 64cc TBI heads. Shouldve known since the engine is a TBI. I didnt get to look for the casting number BUT by the casting marks on the outside of the head i see the double bar. www.crankshaftcoalation.com says the casting num. is 193 and even has pics. This head is not recommended for high RPM performance unless serious port work is done. Anyone know what kind of port work would need to be done to make these work?
