It's not the head that gets the truck sideways at 60.
Swapping heads is not cost effective. You would do much better spending the money on a cam. I would recommend a cam before I'd suggest you ship a head off to have it ported.

The 4 valve change was probably as much marketing as anything. It makes a big difference in normally aspirated engines because more valves equal more flow potential and less shrouding. In a pressurized system, strength matters more. The 2 valve head is very tough. Machine the intake log off, porting, larger cam as Dave said, you have something nasty! (that's my plan)

I have two buddys both p pumped 24 valves, both of them with very little money in them. both also will turn sideways at 60 mph with roll on throttle. ones a 3/4 ton 4x4 with bumpers and 35s and the other, an extended cab dually posi. this is a ridiculous amount of power. i thought that a stock 24 valve head flowed better than a ported 12 valve. i just want to do whats cost effective. if im gonna spend thousands of dollars porting and shipping a 500 pound head around, proly just gonna bolt on the 24. tell me why i shouldnt?

Nothing wrong with a p-pump 24V. They idle fine and run great. They also get great fuel mileage. I have a p-pumped 24V in my first gen. I just dyno'd at 818.5 with my cam plate almost all the way to the rear. I smoke less than a 350 hp first gen and probably have lower egt's. They may not be setting the world on fire, but you can't fault the pump. Great hp potential and they aren't tweaky like a turned up VE.

It should be possible, but I have never seen it personally.
