Seems you fellas are pretty much in agreement I made a mistake with the Proform rockers. They were recommended to me by the tech at Competition Products.

Anyway, good information, very helpful, thankyou.

Stroke, I might take a shot at graphing the lift vs. crank degrees and then combine those results with the pattern/witness mark I see at the valve tip to determine pushrod length. Sounds like fun. Any particular reason you chose to use an increment of crank degrees and then write down the lift, instead of an increment of lift and then write down the crank degrees?

I know the results will be the same but wondering if looking at it from the different perspectives presented by the two methods - if one makes it easier to interpret the results. Just wondering why you chose one method over the other.
