460 head....D3ve Or D9ve
My current 460 is sitting on the floor waiting for the engine project to start.
It is a 1979 E350 460.
My local jy brought in a 12/73 F250 4x2 Lariat XLT with a 460. Should I grab the D3VE heads off of the 12/73 460 or stay with the 79 heads?
My plans for the engine arr to swap it into my 79 Bronco. I'm not looking for big power but a respectable 350-400 horse. Will the D3VE head raise the c/r better without as much machining work? Or not enough performance increase for the cost?
Thanks to all that have shared their knowledge.

For 350-400HP I'd keep the 400! I actually have such a 400 in my 78 Bronco now. More power is always a good thing so if you want the 460 then go for it.
I thought 400 exhaust ports were terrible until I looked at the flow numbers on a 460 head - ouch! Listen to those that know the 460!

Where as the 400 with a 2 BBL carb and the 2 BBL heads and a milder cam with a 9.0:1 compression ratio was rated at 260 hp @ 4400 rpm. and 400 Ft Lbs of Torque at @2200 RPM.
The 400's original heads will need some porting work to make 425HP. I would try to source a set of early 2V heads either Cleveland or 400 any Pre D5 head, in 75 when the 351M was introduced the 2V casting was changed to a more restrictive exhaust port.

Any head can be modified for better power output, but I agree, I'd hold out for some D0VE heads. I have those on my 460 powered Bronco and they're awesome. They do have the Thermactair bosses in the exhaust port, but you can rip those things all the way out of there with a grinder and not even come close to any water jackets.

Exhaust port cross sections ford 460 iron heads
Here you go.
You can see how restrictive the 385 Series port really is and it is bumps, the thermatic and the side wall.
