your truck has a 7mm nozzle non intercooled trucks have a 9mm nozzle. You can either change to an older head or have yours machined out for the bigger nozzle.
Its not worth the trouble for sure. They are nice tho. I made 297hp with mine. Just find a set of injectors. Once and a while guys sell there medium sized sticks to get some monsters. I almost bought a set of DPP4's for under 300. I ended up going for the 6x16's instead. With patience you can find deals.
