What size hex key do I need to get to remove the plugs in the head? My center one is leaking causing coolant to get into spark plug hole causing misfires.

Figured it out on my own since nobody could tell me here or on Facebook. It's 9/6 or 14mm hex. Had to order one online since no local store carried that large of a hex.

I don't have a welder. It's had a small seep since I've owned the car, just never bad enough to cause problems. If re-sealing it won't help then I will have to get it welded. But for now, just doing what I can in my garage to try.
So since I've been down this road, my advice is to leave the plug alone. Build a dam of multiple layers of RTV around the plug galleys so the coolant can run out of the side drain and NOT down into the plug(s) Welding on the car will not work, in fact, your cylinder head guy might not even have the skilz yo. Head has to be immaculately clean and heated before welding. Better to just live with it and keep adding coolant until it is good timing to pull the head.

The head guy I will take it to when time definitely has the skills. Most respected guy in area, member of multiple winning engine building masters challenge teams, and does head work for a few salt flats speed racers. He makes his own tooling as well. All he does is engine head work, nothing else.
