Joe, there were many different bolt suppliers for GM.  Each supplier had it's own head marking.

Paul is correct of course (Hi Paul), but to help a little we have two different suppliers on our 68 which include one supplier with the letters "R W B' evenly spaced around the inside edge of hex head and one that has two circles with what looks like a E L4 inside those two ciricles. Kind of wierd as the 4 looks like it is boxed in the L so maybe its something else but it is unique when you see one. I believe you can obtain proper marking bolts from different supply houses like Paragon, etc.
