I have a 1967 327/300 HP convertible. I had the valve cover off the driver's side today and took some pics. Car was built April 18th. Here is what I found:
Time Clock 1:00
GM
5
T
3890462
L275
From reading it seems to be the correct head (3890462) that was used in 1966 through May of 1967. I assume the "T" stands for Tonawanda. The date stamp confuses me a bit as one book states Tonawanda heads always used a two digit year date in the date codes. That would make it December 2nd, 1975 (?) or is it December 27th 1965, which frankly doesn't make sense either? Thanks.
