So dumb me pulled out an exhaust stud from the cylinder head

I read on here the best way to fix it is to have the hole welded, then retapped. My motor leaks a little oil from the valve cover, and the head, and the oil pump, and the oil pan, and I'm sure you see where this is going. I want to knock all of this out of the way. I wasn't planning on a full disassemble just yet since my bike doesn't smoke at all. I haven't run a compression test yet, though, so if that fails, then I'll be rebuilding. I've been entertaining the idea of going 592 down the road, so if the compression test is good, I'm going to leave them alone for now.
Assuming I don't have to rebuild, I won't be going any further down than head removal. The Vesrah kit looks like a nice price, but I've read on here it's missing some things, but I haven't read what is missing. I read it doesn't have the "hockey pucks." What are these and how many do I need to replace them? Are they the "Cylinder Head Nut Cover" that PartsNMore lists? Is so, are they even needed? When I did the engine on my 600, the cylinder head nuts weren't covered and were left exposed to the oil.
Does the Vesrah kit include the seals for the shift shaft and output shaft?
My oil pump is leaking too. Does the Vesrah kit include the o-rings to rebuild it?
Does Post 23 of "the thoughts of hondaman" apply to my bike? It's about the rocker shafts.
