e11 3zz with 1zz exhaust manifold

[Noahprince]

Hi all! Have a 3zz e11 but i’m hesitating between putting 1zz injectores or keeping 3zz ones to match 1zz intake manifold+TB because had read that the car can be reading Rich, but having read too that 1nz injector are the gap between these two. Also i can’t find anyone that has fitted 1zz exhaust manifold or headers to confirm they will fit propperly with all their O2 Plugs. Cheers!
