Ok, Im got a stack of parts im going to put on the truck around feb. So far i have a comp 260 cam, 6.1 springs and pushrods, summit 20% ud pulley, mag Y pipe, picking up a set of used heads an milling them .030. The only thing im having trouble with is finding Long tubes for a 03 2500, I know ARH. just released some but I dont have the pockets for them. So any idea what I can do for headers an what kinda numbers i should be puttin down.
