No 4V.
These may be service heads.
Is there a way to tell if they are?
Hi S412Gofast, because the heads have a December 1966 casting date code, they could be either - Production for a 1967 GT350 or a service part. Because it has the 65 cast into as well, I'd guess more likely a production head for 1967. The service heads with C8ZE are definitely service parts.
