Reaching plugs with Hedman headers

I hadn't had that trouble, have they changed the bends?

Don't be afraid to modify tools. "Back in the day" I've changed plugs on several cars that for reasons or another had difficult plugs. Took an old box end wrench, cut it, and welded the stub box end back on the remaining wrench "at whatever" angle it took. Heated and bent them---with a propane torch and a vise. And I've STILL (from the 70's) got one 13/16 socket with a HEX rear so you can get a box/ open end onto the socket, and I SAWED the socket off so the thing, when on the plug, barely covers the hex. This allows "tipping" the wrench onto a socket in a tight place. And take the rubber pad out of the socket, although you must be "careful" not to break plug ceramics

Make sure you measure it with the extension inserted, otherwise the plug may extend into the drive square and make the socket too short!!!

You can also take a 13/16 socket, and cut it down, weld a handle on, and make a "deep" box end wrench. This is best done with a 12 point, and carefully position the handle. You can also take a "scrap" small socket, say 1/2", and weld to the side of a cut down socket to make a 'crow's foot' box

Or maybe certain types of "crow's foot"
