Welcome CaffeineTripp! Sounds like you've got quite a project on your hands, there! I learned from my own car last winter just how bad you can get hurt by burnt exhaust valve(s). My first tank was in the 20's and it wouldn't even idle at a stoplight. But after replacing the engine, the mpg kept climbing until mileage in the 60's was almost expected.

That brings me to my second point; I originally tried to get by with just a valve job, but after an oil failure that cost the newly rebuilt head, ended up putting a whole (almost) new engine in it with only 7000 miles. So, before you commit to rebuilding the one you've got, it may be worth your while to check around a little & see if you can find a low miles used engine. That option ended up working very well for me.
