Cracking an Al case doesn't have quite the impact to your wallet as a Mg case. So, what is he looking at inside the case, Bruce? Verify the crank is in spec. Check lash on the IM although from what I've read, this doesn't have too much impact. Possibly upgrade the 4 rib oil pump to a turbo but 4 rib is fine, no? That leaves bearings which are relatively inexpensive. Have the case cleaned and the piston squirters checked. Other stuff like mains shuffle pinned and boat tailing cranks are for race builds. Seems to me like cracking the case is a no-brainer.
