air gap install, guide pins on deck!!!

Those side gaskets may or may not work depending on the heads, gaskets and the milling. If I use the supplied cork end gaskets I can't get the bolts to line up. I have to use RTV, and a very large bead. We have tried many kinds over the years, and the best one we found was from GM. It's a grey silicone that you can use in a caulk style gun. It never leaks.
