Just asking, but why are you looking for anything special? Just ask your local mechanic, or find one near you. I dont know exactly how far you plan to "rebuild" your motor. But at least my job, when we do topends, we just pull the head and send it out to get the valve jobs done. So either way the shop wont be doing the machine work. Unless they have a machine shop there. The valves need to be matched to the seat, so local mechanics probably wont do that. Ill probably be rebuilding my motor, and its pretty straight forward, hopefully if they made a living thus far working on cars they can rebuild a motor. Again im not real sure the extent you plan to go, if your just looking at new valve train, or pistons/rings/rods then a local place will be fine. They will probably send out to get the boring done if need be as well.
