If I am switching to a FAST intake what all do I need to keep from my LS6 intake since I will be selling it? Thanks

Gaskets too. Be careful of the thick black washers FAST supplies on the long manifold mounting bolts. They like to fall into the #7 hole... Be careful.

Not sure if you got a used one or a new one, But whatever you do MAKE SURE you install the correct FAST valley cover bolts prior to installing the manifold, it is a mistake we have to correct far to often for customers

If you don't have them Comp cams ships quick. I bought my intake used and did not know about the button heads bolts for the valley cover. Good point EFI

I re-used my stock intake bolts. I painted the FAST valley bolts since they are so prone to rust. I would personally use the FAST intake gaskets, they are stiffer and cost less than GM.

I assume this is a FAST 90, if so you will need to re-route the PCV fresh air line as well since the TB has no provision for it. Also, a TB coolant bypass is necessary as well.
