no the heads won't work. check around on Craigslist, a set of 350TBI heads could be had for maybe $100 and remanufactured heads can be had from builders for a few hundred. Use the 350 injectors, get a new EPROM from the donor truck if it's the same drivetrain or somewhere like
www.tbichips.com. Everything else is a direct swap. If the later truck has a serpentine set up use it too. Let us know how it goes.
