nothing wrong with the engine, why pull the heads ?
replace valve seals and timing chain set as well as the oil pump drive shaft - does the one with the metal sleeve fit the stock pump ?? Probably better than the plastic junk....

Throw a compression test on the thing before you do anything else. I'd bet they're all decent. Be careful-- whileimhereitis.
You've got the pan off, the manifolds off, pull the heads, and "gee, I'm here, I may as well toss a set of rings in, Oh, darn, the cylinders look worn, I better measure, OOPS, I need to bore, Well I've got the crank out, I'll check it, I need a crank...."
You get the idea.

58K OE 72 BBC runs OK w/ slight puff on startup ... I&E manifolds already off.
Pull heads ... clean em ... check guide-stem wear.
If guide-stem OK ... hand-lap valves w/ compound ... replace seals ... replace 35 year old springs.
