There are three varieties of the C8AE 6090-J. The ones used on the drag cars had eight bolt exhaust bolt pattern like a 427 Low Riser. Production heads started out with 14 bolt pattern so that the 390 GT exhaust manifolds could be used. Around January the production cars started receiving the CJ exhaust manifolds that needed a 16 bolt pattern on the exhaust side. These heads (at least all the ones I have seen) have dates between June 1967 and December 1967. The C8OE 6090-N heads seem to have dates no earlier than January 1968.

I would guess that a set of those J heads that were not cracked or milled excessively could sell for $1000 in rebuildable condition.
