Degreeing Cam by Measuring Overlap @ Lifters

I've got the degree wheel kit and everything ready to go, just hung up on this overlap versus intake lobe method in my head. Before I remove the old timing set I am going to degree and write down where everything is so I can compare it later. I already know the overlap is not at TDC using 318WillRun's method. This kind of stuff is really fun for me, thanks for bearing with my newby questions.
