I have a set of K-Codes heads that are marked cast in 1968 - I am gathering they are either replacement heads or possibly from a early 68 or late 67 k-code engine?
The weird part is you can clearly see where the head should say '289' instead is cast '302' on the bottom but the 3 & 0 are ground off but you can still see the 2. They are definitely 289 K-Heads there is the cast in spring pockets, screw-in studs & markings of HP on them.
What is the real story?
