What is the best way to seal the intake so that it dosen't leak ? I have new gaskets. Are the front and rear rubber ones leak problem ?

 

Front and rear tend to "smash" out of place and then do leak. Use silicon / RTV.

 

X2. I don't even bother with the rubber end seals any more. Hint: The silicone bead on the block needs to be tall enough to seal against the intake, so don't skimp. I also let is skin over for a while before dropping the intake into place.

 

OK. Thanks for your input. Which RTV should I use ? Red, Blue, or Black ?

 

This stuff is the best.
