Is there a market for those old 7/16 header bolts?

I have a couple small cans of header bolts around here. I did prefer the 3/8" hex bolts. They are different lengths too and the longer ones held the torque set better, but they ALL need re-tightening 3-4 times after heat cycles. No memory if they came with header sets, or I bought them aftermarket.
