Intake/Exhaust Valve Brands

[Z2 D2]

Looking to get a set of 75-78 280z valves for my p79 head. Shopping around it seems like the brands that offer the valves are ITM, DNJ, Unknown vendor on z car depot or the more expensive options california datsun SS valves, and supertech. 

Other than NOS Fuji am I missing any brands here? Also, does anyone have experience with ITM or DNJ parts?

Thank you,
