If you pull the heads the head gasket will indicate whether it has been rebuilt or not. Also if it has oversize pistons. But get real. It hasn't been rebuilt. 94K miles from a '70s car would typically get you a little oil burning from valve guides or at least valve stem seals while the piston rings would typically last a little longer. What you're describing sounds to me very much like what I'd be doing to keep a higher mileage car on the road.
If you want to drive it for a while without taking it apart you could probably replace valve stem seals while leaving the heads on to cut down on oil burning and plug fouling.
Engine rebuilding or replacement is a big job and usually not attempted by your average golden-ager (not the old weirdos on this board) and if it had you'd hear about it or run into receipts.

Another quick check is to whip off the valve covers and look inside. A rebuild should be clean in there, and 94,000 miles would have at least dark oil & surfaces, and likely some oil build-up. The reason I'd take both covers off is to compare heads, in case one had been worked on but not the other, which to me indicates someone only did the minimum to keep something running. If it has good, even compression, doesn't smoke or leak, and has good oil pressure, run it until next year.

First I'd look in the oil filler cap area. If it's shiny clean, someone's done some work to it. Next do like Mr P says and pop the Dizzy cap, grab the crank dampener pulley and rock it back and forth. If the rotor moves smoothly without slop it's been freshened up in some way. If it's sloppy, You'd better get a new chain in there before the stupid nylon teeth break off and causes your chain to slip.
