It sounds like they're period-correct fastener headmarkings. If you were expecting the headmarkings of the 2 bolts to match, forget it. Bolts of different lengths usually did not have matching headmarkings except by "accident". Generally, different suppliers provided different length bolts at any given time.In Appreciation of John Hinckley -

HI GREG,
What colour are the bolts. Judging guide states black oxide. Is that correct?

The vast majority of bolts that were used as part of engine assemblies were black oxide or black phosphate-finished. This was especially true of bolts that were to be painted. In the case of the thermostat housing bolts, they were to be painted, either engine color or, in the case of aluminum manifolds, painted with aluminum paint with the thermostat housing.In Appreciation of John HinckleyComment
