Yes those numbers are all over the place. Are you trying to check where the intake center line is installed or how much advance you have. Just go up to max lift and stop about .010 before and after max lift. Check the degrees at those points and add together and divide by two and this will tell you where the intake lobe is installed in the engine. I would think you would want to be at about 110 to 112.

Thanks, Keith
