Are you torqueing down the intake in the correct sequence and in 3 separate steps? Doing the torque down a 1/3 at a time and in the correct sequence lets the intake settle down to the heads a little at a time and with an even pressure on the gaskets. If my memory is correct, it's 17 lb/ft total for the intake bolts but be sure to double check that. I do 6 /12/17-18 for the 3 steps.
