Intake and Valley Pan
I am putting together my new motor. I am using a valley pan with an after market aluminum intake. (edelbrock). I am having trouble with the rubber gaskets on the ends popping out when torqing it down. Also, am I supposed to be using any sort of "goop" to help seal the gasket. What I mean is do I need to use something around the valley pan itself or do you just put the valley pan in and put the intake on top of it and be done?

For the end seals I use this, the pressurized can makes it a breeze to lay down a nice bead.
Permatex® the Right Stuff® 1 Minute Gasket™ GREY
The last time I installed my intake I used intake to head gaskets and the Permatex, no leaks.
I've used valley pans before, nothing wrong with them...just spendy. Seems everyone has an opinion on which is better. I just put a "dab" of RTV on the corners to hold the pan in place.
When you start tightening the intake bolts, make sure that you start with the four smaller "inner" bolts first, then go around to the bigger bolts, two step TQ to 25ft lbs.
ETA: Whichever "RTV" you use, pay attention to the set up/cure times. You want to get the parts assembled within the specified times.

X2 on just a thick bead of Permatex high temp copper RTV only, NO rubber S gaskets on either end. Also make sure the alum intake and the block area are oil free, especially where the RTV is going to be. And it never hurts to lightly score up the RTV contact area of either with a little light sand paper action.
