64 has a different angle between the head and intake. So to use 64 heads, you need 64 intake and vice versa for 67.

In 67 they went from 57cc to 60cc I believe

There are a handful of casting numbers between 64 and 67 but 64 and 65 are the same and 66 and 67 are the same. In 68 they changed to open chambers.

920s are the good head. You can also go with a 302 Swirl port as well.
