If it's just a G then it's a 1971. In 1972 they used the G with a small capitol A to the lower right of the G. John

Correct, though both the G and the GA heads used the same casting number (409100) and either casting could have come with big or small valves. Note also that capitol refers to a building and capital refers to the large letter.
