I would put the intake on while it wa still wet that way when you tighten it down the RTV will fill in any low places and the intake will sit where its supposed to on the head.

I don't wait -- as soon as I put the RTV down, I drop the lower intake on it. Never had a problem with leaking ('cept for the first time, I didn't use enough RTV -- always put on half a tube to be sure 
).

I let the RTV skin (about 5-10 mins). Yea ... on the front and rear - use PLENTY! Do take your time - putting the whole thing together, then having to remove it after finding a leak would SUCK!

I dont even use RTV except for on the corners where the front and back pieces (rubber or cork) meets the lower to head gaskets. Everything else stays dry except something on the bottoms of the front and back pieces to hold them in place. Installed correctly you won't get a leak... Not many people do it that way for some reason. Guess I'm too poor to afford a tube of RTV

The first time I put my intake on, I waited about 15-20 minutes on accident. The RTV probably dried up too much because I got a coolant leak about a week later. The next time I waited ~5 minutes and its been sealed ever since. I also let the car sit overnight to insure it was dry before I started it up.

I put a very thin layer around all ports, just to make sure. I used the FelPro gaskets so I am sure it was not needed - but I like to make sure. I have had no leaks of any kind. I too let my assembled engine sit overnight, just to make sure everything was dry and cured before starting it.

You will see tons of debates about using the end cork or rubber, or just making a healthy bead of RTV. Do a search on that. I used a thick bead on the ends, and a big blob in the corners at the front and rear - like I said, with NO problems.

This is the right way to do it. I have never ran the bead across. Just the corners like the directions tell you to. I have never had any leaks. The rubber is made with a number of peaks and valleys and is designed to catch anything that would happen to slip through, preventing a leak. If your prep the metal and make sure it is completly oil free and down to the bone dry base RTV probably would be OK. I just had a bad experience with a huge chunk of RTV that broke loose in an engine and I found pieces of it in the bottom of the oil pan. I dont trust the stuff.
Zach and you are right. There is NO NEED to cake that **** on there. The only thing it is going to do is clog the ports and make a mess. Torque everything down properly, and there shouldn't be a problem. When I put the lower manifold on the heads, I used 4 dabs in each corner. When I mean dabs, they were smaller than a dime.madams74 said:
