An old farmer's trick I still use to remove rust is molasses. Get a big tank, use a 4:1 ratio of water to molasses, and dunk the rusty bits in. Come back in about 3 or 4 weeks. As molasses ferments it has a chelating effect. I've dunked rustier parts than those in molasses and they came out looking freshly cast! I would suggest the traditional methods of hot tanking for the crank, head, and block, but i'd bet the rest will come out looking new!

scrap metal... or shine it up real nice, turn that sonofabitch sideways and shove it up... I mean, lay it on the living room floor and make a coffee table out of it

Too bad it wasn't a 198; at least you could have saved the rods.

Doesn't look like the exhaust manifold is cracked. I'll bet the head is salvageable especially if oversize valves are used.
