Intake Manifold Gaskets, and intake vacuum leaks

I have only had my intake on my car for four days, and the instructions a friend gave me on the torque sequence for the intake were wrong, so what are the problems torqing the intake down wrong would cause. I assume it would create vacuum leaks, and other probs, is there an easy way to check for this kind of a problem. Also does anyone know for absolute certain if the injectors off of any 4.6 can be used as long as they are the same 19# rating. Also can the gaskets on the intake be used again as long as they are not hurt.



thanks, any and all help will be appreciated,
