air gap install, guide pins on deck!!!
When you set the intake up, be sure to mark the center of the runners or separator wall on the head and do the same on the intake to center it.
I use a front and rear gasket, but I use the foam gasket, with black RTV along the entire back side and at the corners. I've found that this sets up much quicker and lasts longer than just using RTV. Do NOT use cork, unless you want a busted intake at the distributor opening. The aluminum can't crush cork.
