I think a bolt on spacer is your best bet.

Perhaps find a machine shop w/ that could machine a recess in the end of the cam on a lathe. Then they could machine a spacer of near the same O.D. that would fit.

You will have to drill and tap either way as you will need the bolts to drive the oil pump

If you never intend to use an air injection pump again, you can simply drill the end of your cam, install 2 bolts, and bolt the oil pump directly to the cam carrier.

That way, you wouldn't need a spacer, and the only seals would be the paper gasket on the cam carrier, and the oil seal in the scavenge pump. Eliminating the seal on the spacer, which is really only needed to drive the air injection pump...
