Looking to have my 440-1 heads cnc ported. I've called modern several times with no luck. Who else does it? What's the going rate for cnc porting?


Question would be why?
How fast you running now?
How fast do you exspect to run ?
Are you just porting head no other changes?
Reson for asking i have seen stock heads run eddie jr run
Ported eddies run , and cnc ported jr heads run
In several combos from 474 motors to 540
In various cars wieghts
Dynos prove nothing to me as to many have known to be not reliable
As well as many flow benches
What i would rather see is some one that has actually taken thier heads
Take stock ones off run them. Put set of thier so call ported stuff
Make no other changes see what the actual pick up really is
in the real world
