How about doing some diagnostics before you throw parts at it. First thing: You say it has a misfire. OK, a misfire generally involves ONE cylinder not firing every time - or firing weakly most of the time. Second: The things you are doing generally affect ALL cylinders - not just one.
Some things to go over: 1) a compression test will tell a lot. 2) Check for vacuum leaks. Around intake manifold in particular. A vacuum leak can cause one cylinder to "lean out" and fire erratically. 3) Spark plugs: By chance are you using champion plugs? If so, I can guarantee that you will never get a Ford to run right with Champion plugs in it. I'm not condemning Champion plugs al together, just that for reasons I will never understand, they DO NOT WORK in a Ford. Period.
There are some other things that can cause your condition, but then you are getting into major engine work. Items like a single broken piston ring. Or a poorly fitted piston. Or a bore that is out of round. Or a head that is built up with carbon to the point of significantly changing the CCs of the combustion chamber. In some cases, I have seen carbon built up to the point of hitting the piston at TDC and it would sound like a bearing knock.

I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
