Wait, what if the Honest gate keeper tells you, once you ask him, that his lying opposite would say 'going to heaven.' Even if the other is lying, he'd still say the door which leads to hell is actually heaven. So the honest gate keeper wouldnt tell you if he was lying, just what he would say.

Might as well just ask one of them by that logic.
