im just wondering wat you guys use when puttin an intake on for the gasket on the valley of the motor front and back. it comes with a cork gasket but i heard some people use rtv or other sealants. also do you have to run a pcv valve if you have breathers on both valve covers? any info is aprecitated p.s i cant spell
What I do to prevent any shifting is use the cork gaskets but glue them to the block with some weatherstripping cement so they don't go anywhere, RTV is ok in that application but it can shift.

No cork, I use thick bead of "Right Stuff". I let it get a little "skin" on it before I set intake down. Tom, I introduced this method to Ed after his intake blew out 3 times. Hasn't had to do it since.

I always use RTV and have never had a problem. I don't know if they all come like this now or not but the Fel-Pro intake gasket set I just got about a week ago for a 93 Cobra has rubber peices instead of cork. These new rubber peices look pretty nice and have lips on both sides to keep them in place. I may give them a shot and see how they work out.
I know people don't like the cork gaskets and Rob's way is a great way to seal it up nice , But I've used indian head sealent on the cork gaskets to hold and seal them in place . Trick is to let the indian head to tack up and to put a small bead of Black RTV on each corner where the cork meats the intake gaskets and wait till the sealent dry's a little before you torque it down . Also after the first heat cycle .. go back and check all the intake bolts for proper torque again . I've never had a leak after doing it this way .
