360 / 22 = 16.36 (crank gear has 22 teeth)
So if you move the cam one tooth in either direction, you're changing the timing events on the cam by
16 crankshaft degrees (which is where all the timing numbers come from - a degree wheel on the crank).
I kind of doubt that he needs to move it that much - he probably needs a "tweener" - something in the middle. So, I'd try a new cam gear first (to see if it was somehow indexed wrong on the bolt holes). If that doesn't work, then you either custom drill a cam gear (on a mill with the correct tooling), or you come up with a method of increasing the bolt hole size and using some "offset" cam bolt-bushing sleeves (like we used to do before we had adjustable timing chains on SBCs).
Hope this makes sense . . .
