is it worse when its hot then its a possibility
I have seen it on a lot on old tractors where nobody have adjusted the valves for decades symptom to look for it more difficult to start when its hot.
well its some time since I played with 4.318 but for me it sounds like the valves have you checked the valve clearance if you run std exhaust valves the beating and heat can make so the valves are going up in the head so there is no compression when its idle but at rpm they are forced up so it running on all 4
