Been reading the "How to modify Your Nissan Datsun OHC Engine" By Frank Honsowetz.

Reading about valves and their head shape.

It says you can get stock valves that have been modified (Numerically Controlled) in the way they are machined.

It gives a part number 99996-N1100.

I am wondering if anyone knows if these still exist and if so is it worth trying to get a set and paying $$$ or just getting a reputable machinist to cut stock ones the same way?

Good book BTW.

I have to avoid books like that as my credit cards run away and and hide.:classic:

I will call Nismo and ask...have a few friends who work there from my days at Sheehy Nissan.
