I'm going through the same thing now except KB has my money for a hemi block and I don't have a block after two years.

I also need a wedge block. I talked to best machine and they get semi finished blocks from Indy and cut the bores, clearance and deck to your specs. No first hand experience but by reputation they do a good job and they were pleasant and helpful when I spoke to them on the phone.

BG has Indy do all the machining to your specs. I talked to them about ordering a block and getting it at the Indy show (cheapest route) but I am a little uncomfortable buying a block from one vendor and having it machined by another vendor. BG will machine a block at their local shop but it costs more.
