Another forum member wrote up the best how-to on intake installation ever. However, I don't know where it is right off. Someone else will, I bet.
I can post my personal summary though. RTV does NOT stick to oil. Surfaces must be super clean and dry. I do a final wipe with alcohol or lacquer thinner. Take out the intake gasket kit. The end pieces might be simple strips of cork or formed pieces of silicone. Either way I do not care, despise those oil leaking POS's equally, and toss them straight in the trash. I have a set of four trimmed off bolts, one in each corner, that allow me to "plop" an intake straight down on top of the engine. It's a common practice. They are really nice to have but not essential.
Everything clean and ready. Aviation sealer on the water port and place the side gaskets. I flip the intake over and "paint" a coat of RTV where the end seals would go. Just enough to add solid color, like paint primer. Then lay down the fat RTV beads on the engine. Plop the intake down as straight as possible and as soon as possible. Make sure the side gaskets didn't move and add some bolts. Remove my installation studs and put in the rest of the bolts. Torque the bolts and abandon ship for at least the next 12 hours or more. If possible. Thick beads of RTV may appear to be cured and firm on the outside but they really need to cure all the way through. I have pulled some assembles apart hours later and found such big beads to still be totally liquid at their core. You can put the engine back into service sooner as the RTV beads don't have to seal against any pressure, it's just good practice.
