It's not standard, but it is frequently done by repair and especially machine shops to help identify the part separate from its paperwork, or to indicate externally that they once worked on it. It could mean anything from a simple reconditioning to major repair work or modifications.

Some tuners engrave their name into the head after they modify it, it could be a modified head.

I also have some scribbling on my 426 cylinder. I'll try to snap a pic this weekend if I remember.

Both my barrel and head have some etched numbers on them...the barrel from Luke's Racing, initials, month and year (not sure if it was Luke's or the bore and plate house that did it) and the head from Eric Gorr, with Eric's initials and the month and year he did the port work and valve grind.

Mine has the same sorta deal on it. There is 1 set of 5 or 6 numbers and another set of 4 I think. Looks like a 4 year old wrote it LOL.
