As far as I know are 3 "standard" compression heads used in the 51-54 production run for the 327/288 Motors:

288 AT
288 STD/327 AT
327 STD

I wonder if the switch to the new body style in '51 also brought forth the "Thunderbolt" usage. I am beginning to belive that the 288 Thunderbolt, 327 Thunderbolt marked heads are the ones that came with the cars when the left the factory. Then non-thunderbolt heads with just the 288AT, 288 STD/327 AT, 327 STD markings, were the service replacements versions.

I guess we would need everyone to take a picture of their head, and note down any markings (casting numbers, dates, P/N's, etc), and lets see if we can figure this all out. Eventually a pattern will shake out.
