If the block was run through the "Shake and Bake" process, I assume that means thermal cleaned. Hopefully, when they were done, they ran a ball hone through the cam bores just a pass or two. The blasting part of the thermal cleaning process will close the holes just slightly and lightly abrade all surfaces. Every threaded bolt hole needs to be chased, the mains will need a line hone and the deck will need a light re-surface to restore them. It's just part of the normal process. Great way to clean though. Good luck with it. Generally pounding new bearings into thermal cleaned blocks not prepped, results in tight cam bearings. Cam should turn with 2 fingers with all bearings installed and light oil. Good luck with the build.
