1g head identification

[tunerdoc]

i have a 1g head with cams and can't figure out what year it is.
I looked for the a c d markings on the cams at the #1 cylinder side no markings.
Any thoughts on what year it is. Should I just measure the cams lobes.

The markings are on the #4 cylinder side, aka CAS side. To find the markings, look at the end of the cam as if you were looking through a telescope. It's in small print. If there are no marks then it's a 90.
