procomp bbc cnc heads wondering who all out there has got them. i got a set but havent fired up the motor yet. just checking i you guys was happy with them or not. they claim that they flowed 412 out of the box and my only flow 380. i was kinda unhappy about that. but they did flow alot better on the exhaust side then what they advertised. sure would like to know your input on them and what kind of power you guy made out of them

its the same casting as the RHS head... actually we compared them and not much difference at all....
he runs 6.16-6.25 - 1.35-1.37 60' on motor in a ladder bar car... bracket racing race weight of about 3200-3250 since we added ballast. big tire car
on a double cross plate with 88/88 jets it runs 5.5x.- 1.23 60'
69 camaro with strut front end. 36" of stock frame rail under it.
heads are pretty good and a good price.
