Never done this before but have been studying up a bit.

Is it ok to use the springs I have on my head (Dart Pro 1) as opposed to putting check springs on? A friend of mine had stated check springs can actually fool you and are not as accurate in using them.

Also, where the instructions speak to the point about 'pushing rocker down so valve makes contact with piston,' do I actually push down on the rocker or can i use my hand to push down on spring?

Lastly, I'll be using roller lifters so is it ok to use the roller lifter for this test? Thanks Bobby,
