So last year I received a pair of "SpeedMaster" Heads as a gift.7/20/16
I then heard a lot about intake pushrod angles and they need to be opened up..
I know Hughes offers 75 bucks a side plus shipping to CNC them correct
I also pk'ed up their off-set rockers..
meantime I emailed speedmaster former procomp about this and they said they have since corrected the pushrod angle..So
today I did a real quick mock-up and low and behold I see no binding at all..

I'll keep ya'll posted

Interesting....I was just looking at those and trying to justify trying a set. Hughes is running a pretty good deal on CNC porting and supposedly they take the Victor program. Could make for a screaming set of heads on a budget.....which I still can't justify. Lol! Let us know how they work out for you.

I bought a pair of fully cnc`d procomps, they used the victor program, because they are the same head physically. We did change the retainers and keepers tho, springs checked out good. The cnc`d pushrod holes were way bigger than those in the pics, but I still had to work on the holes 3 times to get clearance ! If it weren't for the "rape shipping charges", it would be better to have hughs do it. But, would they clear then ?? The only thing I don`t like about the heads is the spark plug holes aren`t heli coiled, and #7 is right perfectly lined up w/ my steering column, and very close, have to jack engine up or move the steering column to change it. If I ever have that head off, it will at least get a heli coil in that hole ! I had to order 9.400 long pushrods for them w/ the solid roller set up, and have an extra new set if u need some. P S, setting the rocker asemblies up was the biggest pain in the drain for me ! Think I`d use springs next time !
 
I am anticipating having to remove more "by hand" if need be, I have been..
 
NO Pushrod pinch w/plenty of wiggle room before setting lash
1.5 Rockers

so aside from setting up Rocker Arms which you do in most cases anyway...
Happy Holidays
