hey guys it's been several years since I changed RB intake manifold gaskets.

do I use just the valley pan or do I also need to use side gaskets.

If I remember back to my youth, I would normally just use the valley pan. in fact it wasn't until I first installed a tunnel ram back in 1999 that I can even remember seeing side gaskets included in the valley pan box.

I will be installing aluminum intake if that makes a difference.
