You've indicated that the front two cylinders have compression. We'll assume that they are getting fuel since you've cleaned the manifold and worked on the valves for a while. (You did set the valve clearances, right?)

If it has compression and fuel, all it needs is spark, and proper timing. With the engine running (sort of) take a long screwdriver and put the tip of the blade against the block. Then bring the shaft of the screwdriver really close to the metal cap on the end of the spark plug wire. If no spark, it won't run on that cylinder. If that's the case, check the wire and the distributor cap. Check both of the front two cylinders that way. If you have spark, is there any chance you have those two plug wires reversed?

Another, more remote chance, is two bad plugs. Try swapping the plugs to the other two cylinders and see if your problem continues, or moves to the rear of the engine.

Keep chasing; you'll catch it!
