ProComp/Speedmaster aluminum heads
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).
