What specific clay to get to check PTVC?
Don't use playdoh - it is reslient and will not hold the compressed shape and will not show the actual PTV.
Also, I recommend the dial indicator method. It is much more accurate. I had a very hard time getting any type of precise measure using the clay method. I tried using different measuring instruments (micrometer and caliper) and could never get the type of precision that I was looking for. Just me $0.02.
Good luck.

I was going to use the sping method as shown in this write up

Oh you know what I completly forgot about that, I have had way too much crap to read today, I will check my email again. 
Edit, checked it and all I got was how to rig up the lifters and trays, I sent you a email...
Also is this the type of clay I could use? I want to check the ptv as many ways that I can.

There are 4 Hobby Lobby stores in OK City. Just pick the one that's close to you. They keep it and it's cheaper than ebay.

I checked PTVC in my engine by installing the heads w/o head gaskets and rolling the motor... It's not the science lab way to do it, but if it clears w/o gaskets, it should be good to go with a gasket.
Now thats something I would have a hard time doing, esp after dropping $1500+ in heads and the time to change them out
