Puzzled? I think you are forgetting that not everyone has the run of a machine shop like you do Snow.
Most of us don't have access to a lathe with the correct fixture for cleaning up the head sealing surface, the tool for checking the valve spring strength, etc. so it's easier to have a pro do it.
Years ago I checked to see what the local machinist (who did Porsche heads on occasion) would charge and Anchor Atlantic could do the whole job (2 day turnaround!) for about the same price as the local machinst would charge for just machining (no assembly, disassembly, setting valve spring height, etc).
As for his 3.2 heads, they are great right out of the box (they will flow enough for 300hp I'm told) so it makes little $ sense to modify them especially for a stock car.
