RE: 289 heads decoded?
The casting number in the 1st picture looks like C8OE, that would be a 1968 head, with a 63cc combustion chamber and 1.67in intake valve and 1.45in exhaust valve.
The 2nd picture with the 66 head, that 6A24 isnt the casting number. A 66 289 head will probobly have a 54.5cc combustion chamber and 1.67/1.45 intake/exhaust, or a 1.78inch intake for the HP289
