I’m my eyes they have been basically tested improperly by several running “baby lift” cams.

I have .606 NET lift on iron heads for a street/strip car.

If I was doing TF’s I’d run a a roller and if the valve gear would take it, I’d try to net .700 lift with them.

Way too many guys running lifts like that on street/strip stuff and it lives.

Lift is like compression ratio. You use as much as you can get with what you have.
