Good luck trying to find oversized cam bearings, I bought the last set Dura-Bond had a few months back. If the bores aren't to far off you can use an old cam with spirl grooves cut into it and use it an a reamer. Now if the block has a lot of core shift you need to find someone around you with a Rottler F65 or 85 can't remember and have the shop bore the cam housing .010 over for the special bearings.
