If you are talking about the 8 o-ring style gaskets on each runner that seal against the head, then just buy an intake gasket set from one of the auto parts stores or from GM. They will work fine. Make you have the button head bolts on your valley cover. I'm not sure what gasket to use for the 90mm throttle body. You can probably buy an LS2 TB gasket.

Well that sucks. If you go OEM, go new and don't re-use. The FAST gaskets were a bit stiffer rubber than stock, if you have parts stores that have them in stock you could check to see if they are as soft as the stock ones.

Be more specific - are you talking about the 8 port o-rings or the throttle body gasket? The LS1/6 cathedral head ports don't care if you have a 78mm, 90mm, 92mm, or 102mm throttle body opening.

They are in fact a lot softer than the FAST one
I tought that i could put a small bead or rtv in the groove of the each intake port and then put the seal in.This would make them a little bit thicker and less prone to compress...good or bad idea ???

I wouldn't do that. See what Fel Pro and other have if you can find them to look at. Do you have the part #?

Found these on Thunder Racing's web site: Link

Found these on the "other" site: Link
