There are several shops that can do bore and Hone with torque plates. Not many with fixtures for correcting lifter bore alignment (MadCap) or installing aftermarket main caps.
The shop I used outsorced installing the main caps (got me a better price than when I called around), but I don't know who did the work?
The Block Shop is pretty good for the basic stuff, I have used then several times. I recently used them to machine my 505" stroker block. Align honed the mains, Bored and honed (with torque plates) the 440 block for 0.030" pistons. Measured the crank, rods and pistons to square deck the block for a zero deck height at TDC.
The other shops listed here in Denver, Ridge Reamer, Slatton have good reputations, but I have not personally used them.
