No gains with the truck heads. You can buy the head swap kits with everything you need for under 1K now. Beats trying to piece everthing together. You can also do the PI intake and cam swap for under 350.00 and gain 30+ rwhp. Or better yet, pay 1,200 to 1`,500 for a good used PI motor and be better off.
Your choice
