Holden large chamber head with YellaTerra valves, more than likely modified by YellaTerra.

Yes it looks like an early Stage 3 Yella Terra head. They re-manufactured standard heads with larger valves, 'machine porting' (very flash & high-tech in it's day!) and replaced the cast inlet port dividers with steel tubes.
If you look at my build thread I've posted a picture of an early add for one on the second page and a picture of one I'm rebuilding.
