340 heads help

[mostrood]

Hi gurus. I just picked up a 340 for my Duster project. Are these x heads 7/13/67? Does that mean they were used in first year 340 '68? Lastly, is '67 a good year for these? Thank you!

Well, except for the open-chamber design is sorta obsolete.

I recently sold a set of 67 casting X heads, they are in fact for the 68 model year.

Normally there is a letter “X” cast on the outside near the spark plug holes.

Thanks ya they have that. I was mainly confused about the weird date stamp.

Mine were in need of some work on the guides, sold for $500.00 with stainless valves.
