Do I need a solid lifter?

Why are you balking at buying the tool? How much money does the picture in your original post represent and you're going to balk at another 100 bucks or a little less for a tool that can be reused over and over......or even resold? Talk about makin no sense.
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.
