Not Starting

First, I would like to preface this by stating that I have already searched for this issue, but other people seem to have had slightly different issues than me.

Right, so I replaced my cylinder head, and I just put the bike back together sans plastics. When I tried to start it, it would crank, but to no avail (my battery was pretty much dead, enough so that it would die when I tried to start it). So I charged the battery, and tried again: still no start. Then I noticed that I probably flooded it. So I tried starting with WOT to clear it. I did this about 15 times for about 5 seconds each time, then tried to start it normally again. Nope. So I took out plug #4 and pressed the threads against the block and tried starting it. No spark. I did the same with 4 old spark plugs as well, but only with (coil?) (the thing that plugs into the top of the spark plug) #4.

Everything is normal when starting (fuel pump primes, no weird indicators on instrument panel, all lights work, and the starter is engaging). What could this mean? Bad battery? Bad relay? Bad (coil?)? Something else that I could have overlooked? I will take some pictures tomorrow afternoon for reference for you guys.

Thank you everyone.

Okay, I just read another thread, and it is possible that my valve clearances are too tight. I will recheck when I get home. They were way too tight, but I didn't have any smaller shims, so I just put it back together without remeasuring. I figured if it ran before, then it will run again. So it is possible that I have no compression.
This seems like a very viable reason.

Well I feel like an absolute imbecile. I went through and did a valve adjustment (which I guess it did sort of need), and in the process of putting my bike back together, I remembered that when I put the tank down last time it was being difficult. I put it back down and checked underneath it. Sure enough, my fuel line was pinched. Badly. So I moved it out of the way and put everything else back together and tried starting it again (this time with a fully charged battery). Oh how sweet it is to hear this motorcycle hum. It started on the first try, just as if it was another normal start. No drama, no delays, no weird idle. Simply perfect. So if your motorcycle isn't starting, check the fuel line first (unless you need a valve adjustment anyways).

Here is my valve clearance spreadsheet (thank you to dreamzboy for providing the template). Notice intake 2 on cylinder 4. Not even a 0.04mm feeler gauge would fit.
