Markings on 1967 42 Heads

[Kirk M.]

Just thought I would share these new pics of all of the casting numbers I could find on my driver side 3890462 head. Flat and round refer to screw head of stamp. Understand all of the stampings except the "4" on the double hump.

1. Part Number flat 3890462 flat/Date Stamp round C 3 7 flat
2. flat 13 flat GM 14
3. Time Clock set just shy of 2:00
4. "4" Stamped on one of the double humps

On the machined side that mates with the block are these numbers. Not sure what some of these mean.

1. 462 on non-machined surface
2. 462 in recessed area of surface
3. C13 on non-machined surface
4. 12 in recessed area of surface
