Lifter Bore

I wouldn't knurl a lifter bore. It's a temperary fix at best and given the importance of the angles and the .008-.010" it's out - I don't think you could take up the slop and get it right anyway.
IMO - the only fix is bushing the bore. You need a shop with the right fixture, and the block will need to be totally stripped to do it because after you have to be able to wash out the oil galley and oil passages. So no cam bearings or oil galley plugs can be left in. Other than new cam bearings and time it shouldn't cost that much for one bore for a shop with experience and the right equipment.
