What are you plans for the engine? Strip or Street? Or mostly street & some strip use? Those are some serious heads 3500rpm & up. Plus spread ports are hard to find headers for without spending major $$. The Track 1 may be a better choice.

They would work better with a little larger engine but could be made to work with on the 302 or 327. The recommended rpm range for the -8 is 3800-6800 on a 355-377ci engine with a Min. of 11 to 1 compresssion. Those heads would raise the required rpm range higher on a smaller engine to maybe 4400-7500rpm. It would definetly be a screamer,

For your truck you want a head with smaller intake runners that will produce plenty of bottom end torque to turn those huge tires.

The old style dome pistons usually don't clear with the newer heart/kidney shaped chambers. You could check them with modeling clay, just be careful when rotating the engine if you feel any resistance. You may want to do this with only 1 piston installed at a time so it's easier to turn & feel interference.
