Default At a crossroads - AGAIN.. Cam Bearings

After close to 200 runs into the season (which had been going extremely well), the front cam bearing left the chat in my MR1A block. Come to find out every cam journal measures greater than 2.032" (one was as wide as 2.0327, over .002 out of tolerance).

Has anyone had direct experience with finding a solution to this, or is this a case where it will need to get bored/resized for either an oversized bearing or just scrap all this $#!+ and push a 50mm roller bearing in it and be done (then new cam, push rods, etc)? The cha-chingas are adding up fast and making my head spin.

The other option sounds much less entertaining - ordering dozens of bearings looking for a few 2-3-4 sets (in hopes) that they would give the proper crush (0.004-0.005)? This sucks!
