I just took a road trip to a transmission guy 50 kilometers over. Bought a tail section for a 4wd A518 ($45) to replace the OD planetary gears in the A500 I'm rebuilding. We came to talking about camshafts (as you do) and he mentioned a guy over here who does re-grinds. It's kinda steep, around $300 but there would be no shipping, essentially.
They won't be able to do a whole lot about the LSA, maybe a couple of degrees.
If they can do lifters too, it'll probably be a winner.
