Degreeing a Cam, or not.....

I will redo all the numbers again tomorrow or Tuesday. Another thought or question. I have both rockers on. Turning the motor over is a big pain and I feel that there may be some spring tension or compression. It is about time for adjusting the valves. Would it be wiser to remove the rockers so that I could rotate the engine more easily? I would not want to remove the heads. I
Can then measure lift directly off the solid lifters. I have an adjustable rod that I can use if needed.
Thank you everyone for all the advice, help and encouragement.

You are doing fine at measuring lift at the valve spring retainer washer.

Lift measurements start when the valve begins to move, (and end when the valve stops) not at the .050 ths point like when measuring duration degrees.
