Interesting 8BA

[RalphM]

I’ve had this engine for about 15 years, stored in the corner of the shop, and I kinda forgot what it was. Fast forward, someone is interested in acquiring a Flathead and I thought this would be a good candidate. So I pulled a head to check for cracks, not relieved, copper head gaskets, and an industrial engine tag I hardly noticed when I put it in the corner. Also does the casting number account for anything?
