I've done a rebuild and it was a lot of fun, in fact I'd consider it my forte when it comes to mechanics.
As a result I can promise you'll spend more than you think, but when the engine starts you'll feel immensely satisfied.
I would change rings and big end bearings and main bearings depending on condition. Also, do a proper job on the head smoothing as much of the rough casting out and getting rid of all the carbon.
I find mild acidic floor cleaner is best for cleaning all the internal components, mine came up looking like new

My engine suffered the same failure as the one you've just bought and I believe it's still running to this day after I finished with it; I fit it to someone's rallye.
I'm sure you'll have fun bringing it back to life
