dont use the rubber thingys, use a TON of rtv, and dont just run it on the block, run it up onto the heads a good way to ensure a proper seal. let it sit overnight before starting it too to give the rtv a chance to cure. If you do that it definetly shouldnt leak.

Intake Issues?

Yup, when I bougt my crate 350 from GM, the counter guy said to ditch the "wall of china" rubber gaskets and use a nice big bead of black RTV, and to overlap the intake-to-head gaskets at the ends of the RTV beads. So, that's what I did, worked for me. He said those rubber gaskets are crap and that they'll either leak right away, or leak later.

or you didnt clean it well enough, and the RTV didnt cure to the block good enough.
