I'll let you reverse-engineer the answer from the following: .650" net lift w/ .018" lash and .433" lobe

Since you may be mathematically challenged, it's right about .020" net lift.

Fixed... and I have no idea since my P O S hasn't made it back to the track w/ the new engine build, nor will the engine go back on the dyno before the car is running again. wrench

The other thing was I was expecting to use them in my spare engine build (fresh short block) that might also end up with a different cam. The new cam choice would be influenced by the net ratio vs the lift my valve springs can support, and the lower ratio than expected didn't fit w/ what I'd been considering.

How much do you think it would cost you in your... what did Ray call it... oh, yeah... tin can? tonguue
