Ailing engine (Updated after teardown)

Thanks Rob, is there something "wrong" with #8 numbers? Are they actually too high?
Probably. It's tough to call though since so many of the cylinders have distorted fire rings. If I had to guess, I'd say #8 was getting water or oil in, #6 was low for "whatever" reason and the rest were "about right", but it's anybody's guess.
