Gotcha thanks...just didn't make sense to me and wanted to make sure I wasn't missing something. I do have one other question about cam centering. I've read other threads on this topic but not my exact issue so here goes...when I position cam so that there is equal lip showing for cam seals on both sides the cam bearings show slightly different over hang on the inside. And yes the bearings are fully seated against cam lobes. So do I keep equal seal lip or make inside bearing over hang the same?
