You have hydraulic lifters so there is a good chace that one of the #8 lifters has not collapsed back to normal working height yet and is holding a valve open.

My suggestion is to get it running by any means possible. Feel free to jump it with 12 volts so it spins a bit faster. Then get under that fender and keep on spraying pen. oil on those reluctant intake valve stems while the lifters keep bumping them. If that does not work then you will have to pull the head and the valves. Oh, and test all the lifters in case one of them was overstressed forcing open a stuck valve and now can't hold it's liquor any more.
