well, worst case scenario, they could find a used cap from a scrap engine and machine the flat surface down a little to ensure it is flush and allow a slight bit more metyal to machine in the bore, then line bore that hole round again to size, just so the cutting bit is set so it doesn't also cut the block side of the hole. pretty intricate work and work that a lot of machinists will say is not correct to do. or the bore could be made oversize on the front bore only. or all the bores could be line bored and get oversize bearings, if available. the final option is what most engine shops would want to do I suppose. maybe custom sized bearings are available somewhere. the engine fellas should probably know that since they have been around for a bit.
