When good is not enough, Camshaft time again.

Well, I thought I had everything ready to begin the install. Then I went to install the cam and it would not fit into the existing cam bearings. I inspected the bearings with a bore scope and then tried in the old cam and it fit easily so no burrs or dings prevent install. Then I measured the new cam and all the cam journals or “races” are .002-.003 in larger than the old cam. Does anyone have the specs for what the journal sizes are supposed to be? The largest one on the new cam is right at 2.000 inch in the micrometer. Maybe .0005 under. Definitely not .001 under 2 inches. What to do now?
