hi, in S/S , the port volumes and chamber volumes have to be at the stock sizes. like wise valve size also. comp ratio and top of piston have to be same
as came stock. in other words, it has no 14to 1 comp ratio. the heads are reworked to get highest port velocity and flow needed. the stock carb is required. the fact is, its fuel curve in carb that makes it go fast. class racers are very good at finding the hidden power in a combination. they're not parts changers like most guys. any one can change parts to go faster. just food for thought.
