Up on that shelf were some of my old exhaust valves. I'd had the machinist install some fancy stainless valves in my old factory heads.
I bought a bare set of heads from Summit a few years later and had the machinist install larger than stock exhaust valve seats for the larger valves that I bought. I reused the intake valves from my old heads because they only had 20,000 miles on them.
I of course saved my old exhaust valves. It's surprising that the price hasn't changed much in 25+ years. I think these were 12 or 14 bucks then and now they're 18.
