No. I believe it is a casting sequence number.

No. It means the core box the block was cast in had been retooled or cleaned up 6 times. There are no outward signs or numbers that denote a certain type of 440 block. The engine assembly would be stamped HP if it was a performance engine and sometimes with a "1" or "2" designating the shift it was assembled, but there is no telling a standard HP from a six pack based on casting numbers or block stampings. All 440s, from the standard passenger car to six packs use the same base block.
That could be a mold number used to track if there are any quality issues, they can zero in on which mold it's coming from... Like cavity number etc....
