I did read the directions on the can of the right stuff gasket maker, this wasn't my first time using the right stuff gasket maker, I've used it for years, used it on all my differential covers, I use in place of the end gaskets on my intake manifold, I've used it on valve covers before too. It says to cut the tab to whatever size you want the bead to be, I didn't lay a ridiculous amount of it on, but I did lay a thick bead and went around each stud with it.
I don't think it will leak ether because I've always had pretty good luck with it, the only times I have had leaks when using this stuff was when I didn't put a thick enough bead down.
I bought the grease needles for the bearings from Napa today, the part number is 700-1193 and they are called grease injector needles in case someone else is doing this too and needs the needles. They are really thin and look like they will work great.
