line boring is really the only way to get the bores all stacked up actually in line. not saying they arent inline now, just saying if you get a new bearing cap it has to be fitted to the block so it is inline with the other bearings. in all the previous suggestions I was tryig to give an alternative but really, line boring is the correct way. that said, you may wanna ask about if they can redo just the front bearing main bearing bore after replacing the cap with a new bearing billet cap. not sure but I think some of the old inline 6's had all different sized bearing outside diameters so the line bore would be more expensive because the dude would need to set up on each bearing. some of the old engines also used a shim under the bearing cap to adjust clearances. dunno if that applies to your engine or not but maybe something to check out and ask the dude about when he comes to look.
