I'd bet money that it is the ringland. 80psi normal to high normal for a ringland issue.
To do it right, I'd budget $4k plus, particularly if you want to put forged pistons in, which you should if the engine is open. I think mine cost $5kish (the bill was higher, but I also had to rebuilt the transmission and put in a front LSD). My short-block was reusable.
For D, I would suspect more money.
I'm assuming you're buying this car assuming you need to redo the whole thing.
