I agree with many of the previous posts. Its possible that the intake valve is not opening. Remove the valve cover and verify that the valves are opening and you have proper lash. As you know you need fuel and fire. It sounds like you have fire so I would look to fuel (no intake= no fuel for #1).

Valve train possibilities: incorrect lash, bent pushrod, bad lifter, bad cam, broken/bent valve stem (unlikely), faulty rocker (cracked or in the case of roller missing/broken roller assy)

good luck,
