 There's rust on top of the lifters/rockers/whatevers, but no pitting. Is this a really bad sign or just normal for a motor that sat for 30 years?

It's probly normal if the bike sat outside those 30 years!
Before dumping money into the top end,might be a good idea to split the cases and clean inspect everything.
Thirty year old crancase oil with the possibility of water inside is not good IMO.
