Sounds like casting dates to me, but pictures sure would help.

Hi Denny, no auction #, but here's an item #: 372085834460. Never saw heads with those numbers? No biggy. Thanks, m

Re: m121 & j80 heads
Here's a picture. You can make out the "M121" on the bottom head. Notice the casting of the screw head. That is obviously a date code. The curious thing is that there is no model number (8BA, 8CM, EAB), so I can't tell what they are (there may be some that can, just by looking at the combustion chambers which are shown on the eBay auction). All I see is a set of junk heads that had some aluminum paint slopped on them.

Re: m121 & j80 heads
Looks to me like someone ground the markings off and then painted them. The surface looks too smooth, not like a typical casting.
