LS2 Block problem

I am not 100% sure how bad this is going to end up. Problem has got me up at night thinking about this, and can’t pull the motor till weekend. Here’s what I know. Right side bell housing blolts, and the alignment pin are MIA after at Buttonwillow weekend. Slight gap between BH and block on right side. Maybe .125 to .250. Left side bolts are in place. Clutch still works but had to drop the stop some to full disengage. Normal result from gap. There is a hill that unloads the chassis in a twisting manner, that has killed other parts in this area of the car in the past. Clutch, pilot bearing, you get the idea. Anyway, if the bolts pulled out, can the block be drilled and upsize studded on the bellhousing bolt holes? I’m not sure how much meat is in this area. I know the alignment pin can be replaced. Hopefully it did not hog out the holes. I used hardened hardware so if they broke, extraction will be a challenge as well.

Anyone have an idea of cost of a used LS2 block, and maybe a good source if I find the lower corner us busted as well.
