1959 3767465 heads production date .

[Bob W.]

The black books states the 3767465 were the late production head . Can anyone tell me when GM started using these heads on the 1959 motors?

Thanks Bob

According to "Corvette by the Numbers", these heads started to appear in May 1959 and cars built after July 1 SHOULD all be 4765's. These heads were used on passenger cars and Corvettes

Pat Thank you for your reply. So a late June car may also have these heads.
