Edelbrock Intake Issue

Just came back to this thread after a few days and appreciate all this info. Haven't had a chance to read through all the details but will do so this week when I get a chance to work on the car. Something here will most likely work so it's going to be trail and error at this point. On another note, the intake install instructions mention "do not use end seal gaskets." Is that really an issue if I use end seals instead of just a silicone bead?
