So I ended up buying a used 460 out of a 1969 Lincoln continental and I went and had the heads rebuilt and noticed 1 of the heads is D0VE and the other is C8VE. Is this something that I need to correct before rebuilding the engine? Or can I put those on as is?

 

C8, C9 and D0VE-C are all identical and interchangeable with one another.

 

You might consider finding another old head with a matching number just so later someone does not dog you on that
