As Tim points out any machine shop CAN do it the 'right' way. The problem is finding a machinist that WILL do it the 'right' way. Here's a hint: If your vavle shims vary >.005" from valve-to-valve, I can guarantee the machinist didn't put much thought into it.
At first I was a little angry when I had to order 6 of the exact thickness valve-shims. However, once I watched my machinist do another head of mine, I really gained an appreciation for the art. Problem is, I never told him what to do.
Let's not forget the lack of any clearance on 3 valves.....a lot of effort figuring out how to shim these valves is nothing compared to what a dropped valve will do.
