I'd still use the paper gaskets with a light coating under the pan, then put a light coating on top of pan and place the top gasket onto that. Then apply the 1/8" completely around the port openings and the heat crossover. Let this set up over night and drop the intake on, push it down and tighten from the center out. Make sure you alternate from side to side as you tighten it down. If this doesn't work, I hope you're not trying to put a 383 intake onto a 440. (just joking).
