340 Heads,
I think, or seemed to recall, for some reason, the heads off the later 68'
model year engines were a 'touch' smaller in cc volume. How and why, I can't remember. It may have been just a 'needle-in-a-haystack' set of heads. Casting #'s were the same. But of course back in 69'/70'/71' the NHRA Tech people weren't so 'picayune'.
