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

These heads are on E bay & i just wondered what they are. Not savvy enough to bring the pics to the Barn. No big deal thanks anyhow. m

Do you have the auction number? I'm sure that would allow someone to grab the pictures; I've done it many times.

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

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.

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