Would like to hear from someone that has swapped over to stage 2 heads. I've got a 2000 F350 4x4 that has 185,000 miles. I'm currently going through it and upgrading several components. Have put on an adrenaline high pressure oil pump, 5 inch exhaust, in the middle of upgrading to irate diesels competition fuel system. Ordered a larger turbo. Now I'm considering upgrading the heads prior to replacing injectors. Gonna pull them anyway to have them checked out and at a minimum replace the injector seats and put in new seals. I can afford a set of stage 2 heads but wonder if it's really worth it. The truck is my daily driver and it'll be used to tow a fifth wheel camper, a trailer with roughly 8000 pound loads on occasion, ect. Not looking to exceed 550 HP, so the question is would the heads really be worth the expense?
