Check My Cam Degreeing
OK on the pistons. I come up with 11.1 Static CR. I suspect the valve pocket volume is not being put into the Wallace calculator, and that is why your numbers are high. Roughing in some cam numbers from the MP cam, it looks like around 8.2-8.4 DCR at an ICL of 108.
Are these milled open chamber heads? If so, then it sounds like the heads have been milled about .040" and so the head cambers will be about .070" deep + or -. With the head gasket a .035" compressed, and the piston dome up about .065" above deck, it would be about .040" dome to head clearance. Is that the setup?
BTW, on measuring the angles for equal lift on opening and closing ramps of the intake lobe, you want to be on the steepest possible points of the ramps for the best accuracy. At the steep points, the lift versus degrees of rotation is the highest and gives the best accuracy in the way we tend to measure things. Being .050" down from the lift peak may not be the steepest part of the ramp and so accuracy may suffer.
