I have a 360 stroked to 408 that is running a comp cam .575, .575 lift and .308,.308 duration. Currently i am running 1.5 rockers and I am considering going to 1.6 rockers. Was wondering how to figure what the additional lift would be if I were to make this change. Also how much if any would that change the duration. I am also thinking of changing my 915 slightly ported heads to my edelbrock aluminum heads at the same time. I know either way i will need to check valve clearance with or without the rocker change if I do the head swap.
Thanks Rod
