Black or copper rtv has always done the trick for me.

yea that's right it comes in the kit!.. just enough to do the front and rear of the lower intake...do not use it anywhere else...

FYI - gm actually revised the gaskets 3 times they no longer offer the 3rd revision from GM but rather they now only offer the 2nd revision.

If you want the best gaskets you need to buy the more expensive Felpro set as you can still get the crappy gaskets for less from felpro which can be a bit deceiving

if you dont wanna use the sealant that comes with your gaskets the only type I would suggest is Ultra Black RTV
