Personally I wouldn't lean the injectors in the bore hole of the intake manifold for an esthetics improvement. Having some of the the atomized fuel recombined into a liquid by it ricocheting of the port wall will def cause a power loss and probably incomplete combustion.

Even if that does not occur the injector resting against the port hole edge will chaff into the injector housing when the engine is running.

Just my 0.02
