The Stage V replacement head will be enough and I agree the Ray Barton intake probably makes the most power.

I have a NOS set of cast iron D-4's. (I would assume the last NOS set there is.) The D-4's were NASCAR heads, larger intake ports and raised D exhaust ports. They were Chrysler's highest horsepower heads for the 426. I would sell them for $3,000. Rick 501-519-7425

Todd Marsh and his engine guy have built the winningest engine in that class that was ever done--The customer had won 4-5 years in a row, national Champ, and I did his engine one year--he won another national Champ then the Fords caught up with them so he went to Todd with a good budget--they built a MONSTER CI limited combo--big bore shortest stroke possible--it KILLED the other guys and has won several more national Championships--Call Todd at Moparts Connection--NO he will not build it for you free over the phone with all his tips--Yes he will do it for you and promise you wins--Wheel speed is everything in that game--Call him, start winning! Oh yea, go by the bank first and remember to stick with a builder that has a winning rep at truck pulling--it ain't dragging for sure!

Is it possible to get in the 900-950 range in hp with the iron heads if so this keeps me from any argument since any iron heads allowed.

well you can buy your mopar parts from todd also I have bought several parts from todd and he is excellent to deal with . Just down to earth and honest . Also Todd doesn't try to put on the act, like a mad scientist who has been nabbed by aliens and returned with extra terrestial mechanical knowlege

Very doubtful with stock head castings. Like many of the SS cars, the intake bolts get too close to the port window, and they need to be changed to the 10 bolt style like you see running in SS now. To date, I have not seen a set of iron heads that way. And the most HP I have seen out of a set didn't hit 900hp, and certainly not for $25k...At that level, there are only a few choices.
