Does the cam fit the need?
A larger cam duration wise moves the rpm band up.
Does that fit the build better?

Yes, that is the question that the OP can help to answer. Is this mostly for street/cruise use, pure drag racing, rally/road race, or hauling logs? The cam selection will changed with that, and the emphasis on compression ratio may change a bit, and CR should track cam selection to a fair degree.

If 'twer me, I'd mill the block deck roughly .012" to get the pistons flush to the deck, OR just use the Mr Gasket 1121G head gaskets to get the piston-to-head gap down to a range that is good for quench effect. Once there, then there is a bit more flexibility for cam selection; i.e., you can go shorter if desired and stay away from detonation, especially with those AL heads. And, it bumps up SCR and DCR about 0.2 points.
