Date code on stock exhaust manifold

If you can not read the date code on the original, there is no way to know what was on it.

'Build' dates were not recorded back then, only the day they hypothetically 'hoped' to start the cars build. That is what is on the fender tag.

Small blocks have a final engine assembly date on the front face below the drivers side head, so whatever the date on the manifold was, it should have predated that date for sure.
Does it have headers and you are thinking about switching back to original? Just curious. Or are you are questioning the manifolds you have on there now. A few photos my help us identify them.
Thanks ,

There are stock exhaust manifolds on there now, but I know that at one time the left side was off because the heat shield is no longer there. The car is pretty much original (except for the glass packs which have been on there since the 2nd owner installed them in the early 70's. I've only spoken to him and the 3rd owner who had the car put away in a warehouse for maybe 30 years. I was just trying to figure out what the approx. date should be on these because being a daily driver from Minnesota they are "aged". Different lighting doesn't help trying to see the dates on either side with the motor in the car. I thought maybe someone on FABO that had original exhaust manifolds on their car would give me an idea of their engine build date compared to the dates on their manifolds. I read that they painted the motor with the installed exhaust manifolds at the same time. It's just a curiosity thing with me about this car like others have about correct parts, bolts, dates etc.
