Need help choosing exhaust valves

Hey guys, I'm still s.l.o.w.l.y. accumulating parts for my Vega build (72 Wagon with steel sleeved engine) and have a question about GM original exhaust valves. I have a set labeled "370788" but I noticed a fair amount for sale labeled "3992276". Any idea what, if any difference between the two? The master parts catalogue only shows the latter part # listed.

There was a part number change in the early 80's, looks like they are both the same valve. GM often supercedes numbers so I would not worry about it.
