The board built as per instructions will make over 40 watts with 4 K transformers.

No, I came to my senses and decided that it just didn't make sense. If I could find a suitable OPT it would cost far more than I was willing to spend, and the sheer size and heat load does not make sense in my small house in a hot climate.
The guts of both tubes look about the same, so go for whichever one that you can get cheap. The 6GV5 was on the dollar menu at ESRC befor this board came along and wiped out the supply. There are dozens of other tubes that will work in that board too. Read through the entire thread for some numbers that are plug in compatible.
I just built this EL84 using 25W 7.6K OPTs in Point to Point format...Sounds VERY nice.

807s?
I don't see why not.
It is listed for class AB1 and AB2 audio amp and modulator output.
P-P impedance all the way down to 3000 ohms. No distortion data though so that is an open question. It will work, but how will it sound.
807 is derived from 6L6 with top cap for higher B+ so I would expect it to sound fine.
