Intake Manifold

Ok heres the problem just got the 360 together completely, but the thing will not run. I'm thinkin the intake did not seal when i was mounting it cause it was a lil hard to get the bolts in. Is it possible that my heads have been cut sometime another and now i need to get the intake cut to match if so how can i possibly tell if I need to have the intake cut? Also if ive been turning the engine over shouldn't the spark plug be a lil wet from fuel or atleast smell like fuel and not new?
