'77-'79 200sx.

 

Must have been the earliest head. I have N5800SV used until 07 '77 and W5880 after in the US. I Canada it was U6702SV and W5880. I know that the W5880 was the W-58 head and the U6702SV was the U-67 head also used on the 620.

 

This would leave the N5800SV unaccounted for... perhaps it is your N-56 head?

 

I found it listed as used in the 710 after 11 '76 and used after the U-67 and before the W-58.
