Ram Air 3 exhaust manifold dates

I did a search but could not nail this down.

Are all the original 1969 & 1970 RA 3 exhaust manifolds date coded? I've seen lots go by on ebay claiming to be original, but no date codes. The repops are starting to look pretty close. It sure is buyer beware on evilbay so I've been educating myself on stuff (mostly though this forum) but have read different opinions on this. Some say they shouldn't have a GM3 over the casting code, but I have a GM4 on my original 4234 intake.

Any insight?? or even pics of originals?

Thanks in advance.
