074 Head date codes
 

Are the date codes on these heads that were on Ebay really 1968? They do not look like other date codes I have seen on early 074 heads.

Ebay "1968" dated 074 heads

Don't look like mine either.Jeff

Re: 074 Head date codes
 

other than the black marker...they seem to look like real dates compared to this head which is dated one day apart...what are they supposed to look like??

anyone have a pic of something different??

I thought they are smaller charaters and include the "6" in "68", just like an winter's intake manifold from those years. I know the 69s used larger numberals and included the 6 in "69"

This is a pic of a date code from an "074" head. I thought all the early aluminum GM heads were date coded a similar style? https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

Chevrolet did not necesarily use the same font/numerical styles for casting dates on the same exact type part depending on the date the part was cast(boy was that a mouthful!!)...... for example these are 2 pics of original x-ram intake top plate casting dates which are only one day apart and still very different...

those heads on ebay are almost a year earlier than the others...

Not that that proves anything on the head dates...I'm no expert, but just showing real pics of real parts for comparison...

Per your picture inquiry.
Type [image] or [IMG] (either one will work)..in front of it,and [/image] or [/IMG] at the end of your attachment code below.

I see what you are saying but the dates on the heads look nothing like either of those dates. A one digit year code on a winter's part is much later in my opinion. I imagine the date is 1978.
