i agree re degree the cam. now to be fair to the OP you should add only in reference to the lobe centerline, not what the gears say as they are known to be all over the place...

Op degree is as it sits so we know where it is, then we can go from there

Makes sense. I'm thinking about buying a deck bridge to do it with the heads off.

I decided to go with the .075 Cometics. Being at 10.0 to one with the other changes should be enough. I am buying new head bolts for cheap insurance.
