Should be a 76-77 "S" head from CIS engine. Check the intake port size, should be 35mm.

Are these heads the same as large port SC heads from 78-79?

Mike,
The 3.0 Heads have a larger case stud spacing and will not interchange with the early heads like this 2.7 shown here. The 3.0 also has larger ports & valves.
