Lift has nothing to do with it.
It’s the lift when the piston is near tdc during overlap that causes any issues with v/p clearance....... and that’s derived from duration, rate, and lsa.
When the valve is at full lift(100-120 atdc), on your 4.5 stroke motor, the piston is like 3” away from the valve.
Okay, I will admit I am wrong by oversimplifying that thought.
Substitute this, then: maybe it'll help that I'll have 272 @ .050 instead of 290.
Better? Whatever it takes to keep the idea alive
Either way I gotta buy it, try it and see what happens......
When the rockers show up I will order one and find out.
