ProComp/Speedmaster aluminum heads

PRH said

I wouldn’t count on the Speedmaster stuff to be super consistent from batch to batch........ but in this case at least....... it doesn’t appear the CNC heads get any more attention paid to the way the seats are done than the untouched ones.
Both get the one big wide angle......(and no, that’s not the hot ticket for flow or power).

Hard to tell from the pictures, but it looks like they took the top cut out when the opened up the chamber. I suppose that can happen with the seat cutter. The top cut is way too flat for my tastes. And I agree, the seats are way to wide. And who knows where they are on the valve.

That's why I'm not a fan of running anything out of the box. I wouldn't let a valve job like that out of the door.
