Y70 Head

Hmm, it does appear that this is an Australian spec head, but just because it's not common doesn't mean it's good. It is from an injected car, that's obvious. But since it has the round-port emissions liners, I can't see that it would be all that different that a P79. Certainly not worth any special amount to me, but if you just want a conversation piece...

Maybe it's just me, but a whole lot of people in Datsun-land seem to be preoccupied with cylinder heads. Perhaps we need to admit to ourselves that for anything less than a full-bore race motor, the differences between all these different heads are not all that great. Use what you have, and don't fret about it.

I think this is from a L20a or L20e engine. I believe the blocks for the L6 version of the 2000cc are Y70 block casting. I know the head of the turbos are 05L - I will have a look at Dad's L20e power Fairlady next time I visit. So if it is from a L20a/e then I would assume small ports :(

Yes, this is from the 2.0L L6 and has VERY small ports compared to the 2.8L L6.
