old lincoln? heads, help to identify

[mustang]

i have a old pair of what i think are lincoln/mercury heads with exhaust manifolds. the part# on the head is C6VE.6090-B i have some knowledge of ford part #'s and believe that they are from a 1966 model car, there are no combustion chambers and the spark plugs are almost straight up instead of bieng angled to the side, the exhaust manifolds come up instead of down.

if anyone has any interest in these heads please e-mail me waynesworldxl@yahoo.com
