Some people have used the 440-1 rocker arms on the Victor heads so it must work okay. It might only work on an RB block though as the pushrod angle might be too steep on a B block.

On my MW Victor's it looked to me like a .750 offset on the intakes would be best. Or maybe a .650 offset with an offset pushrod cup in the lifter would also work.

The 440-1 offset is .850 and that would also work on my Victor heads but the pushrod hole in the head would need to enlarged since the pushrod would be pushed over a fair amount.
