While detailing my K Kar for this upcomming summer and documenting parts I developed a question about K Code heads.
The build date on the car is May 65, the engine block is also May 65... the heads are coded as follows;
The Number 21 head is date coded 3L21, the Number 19 head is date coded 3M23, both have 3/4" screw in rocker studs indicating early heads. The question is: I cannot find a casting number anywhere on either head, did I miss something somewhere?
