383 Heads serial #s?

[B-Rode]

'70 Sport Fury 383

From what I could find, head serial # 2843906 (68-70 383/440 B/RB Series) is the only one my car could have. Were there any others?

Thanks

For 1970? I don't believe so.

That's the part and/or casting number. Any other numbers would likely just casting date codes.
