Sounds like I've got the same heads as you but I just got mine back from the head shop. The machinist said that the CNC porting job looked pretty good but the valve job was ****. He said it looked like they did a 1 angle valve job and that the cut was pretty far back (deep?). The spring rates weren't very consistent but usable. However, I'll probably have to shim springs maybe .030 to bring the pressure up a bit to match my intended cam.
Yep. Like everybody says. he price is right and with a little work can be made into some pretty good heads. I started a thread with links to all the Speedmaster head threads. Some good stuff in some. Speedmaster head thread index
