I am not sure if you are running the High Riser or Medium riser heads but in a street engine with a 4 speed and a rear gear in the 3.50 to 3.91 gear I would think something like 236/244 on a 110 to 112 depending on the weight of the car and options. If flat-tappet the lift would be in the .600 lift range minus lash. I could look at some notes from previuos builds and compare to your application but I would need to know the cubic inches, car weight and induction used. Thanks, Keith Craft
