Mismatched head question

Can someone tell me the differences if any in my heads that are currently on this truck? I have C7AE-A for the right head and C8AE-H for the left head. I understand these are date codes and one was made in 67 and the other was made in 68. I really hate the thought of tearing this thing apart since it runs soooo good. I have a 1973 truck with a 1966 block....Me6 something something. I have done the dowel trick on it and am confident it is a 390. The engine has been rebuilt and does not have the stock cam in it. But it purrs like a kitty. I don't want to risk damaging anything with the current head setup, so I will replace one or both heads if I need to. Any information here would greatly be appreciated.

Thanks,

Mike

Mike, Forget about it, the only difference in them from the factory is the year that they were built. I suspect that they both got the same treatment during the rebuild. Find something else to get concerned over. :-)

Except for the year the heads were cast, they are identical. Same chamber sizes, same valves, etc... Relax, and enjoy your ride!
