Hey all, In lead up to a new car project I'll be looking into development of the 250 cylinder head. Information I will be looking to gather is as follows. - Cylinder pot / water jacket wall thickness - Inlet porting for increased flow - Exhaust porting for increased flow - Port flow and continuity - Cylinder pot improvements, continuity and flow I will be looking for a scrap head, which will be used for destructive tests to gauge internal dimensions so please get in touch if you have one for the scrap bin. I would also be happy to run the same tests for the 225 Head and run comparisons. May also be looking for a 250 head in usable condition to build for the car project, again please get in touch. Any interest or questions always welcome!
