Do I need a solid lifter?

I am confused as to how that tool would help my situation with regard to checking valve to piston clearance and pushrod length I can measure the cam lobe lift with a mag. base dial indicator. I have already measured the cam and checked the intake centerline. Now that that is set I need to make sure no contact is made.
Well, admittedly, it won't do THAT, but it is the most accurate way to degree the camshaft. IMO, you won't come anywhere near valve to piston contact. Remember, it's the duration that makes it happen, not the lift. It's the WHEN, not the how much. Those pistons have pretty generous valve reliefs. Even still, you really can't be too careful. That's a lot of money you have tied up.
