Sorry, i posted this over at FTE first - new to the forum.
I just bought this 1971 Custom 2WD 360. (See rad. support question in General Forum)
Anyway, I'm just sure the motor has never been rebuilt before I laid my greasy hands on it. The heads have two different casting numbers: C8AE-H on the right and C8TE-6090-G on the left.
Is the one on the left a CJ? Or just a replacement head? Is it possible that it was produced that way?

Thanks,
