if you want to stick with an OEm option, get the 2015+ headers as they have been redesigned. PPE long tube headers are the best hands down.
I've had good gains with ported upper and lower manifolds. I feel if you are going to the extent of E85, I say do it all. Otherwise, there will be folks who say its not worth the trouble.

Martin at RS Enthalpy recommends it as a stock replacement. Only thing is, i don't know what years, but certain older years require an extra manifold stud

Thanks for the advice! I'll be looking into the 2015+ 370z/Infiniti Q passenger headers. Hopefully the extra stud hole(s) aren't an issue, and hopefully having slightly different headers on each bank isn't an issue. I should also grab a new gasket.
