the heads just say 302 on one side, and there is the numbers 3A12 on one head and 3A13 on the other. The block is at the shop, and I don't have that number right now.
I have searched these numbers and nothing came up.

3A12 and 3A13 indicate that the heads were cast on January 12th and 13th of the third year of some decade. Since the 302 was produced from 1968 to 2002(?) this means that they were cast in 1973, 83 or 93. The casting (engineering?) numbers should tell you the decade.

The block casting (engineering) numbers are above the starter. Ditto on it's date code. This only tells you when it was cast and what block it is, as for the vehicle it was originally installed in, there's no way to determine that.
