A F250 4x4

Sorry Dave, I should have mentioned this with my post. The truck is pretty heavy at 5600 lbs. Motor is a 390 with flat tops and I am running a performer rpm intake. The reason for the intake is cuz I had the motor in a shortbed p/u that I use to play with. The only thing done to the heads is I installed CJ sized valves and I pocket ported the chambers. I should of checked to see if the rpm intake ports were bigger than the C8 ports in the heads. Are they? From what you mentioned in your reply I am better off with the C8 heads as I rarely hit 5000 rpm. I am going to change the cam from a Cam research which I am not too happy with to a Lunati. The cam I have is 218 int and 225 exh with a 530 lift on a 110 sep. The cam I going with is 207 int and 217 exh with a lift of 507 and 533 on a 112 sep. The bigger cam just doesn't have any pulling power. I am also thinking of putting on some headers, any recomendations. Try-Y's or what? Thanks Dave.
