If I read this right, your laying in a thick bead of silicone at the front & rear of the block. Are you letting the silicone set there for 20 minutes or so before setting the the intake on? I've heard guys say that it works well doing that.

I actually have never had any issue with the rubber seals that used to come with the intake set. I'd apply a thin film of silicone, push the seals down into place and wait a few minutes. Then set the intake down as straight as I could and be good to go. Some guys use some short lengths of all thread as a stud to help guide the intake straight down.
