Need some info on intake gaskets

I find the thick black felpros have too much material along the bottom edge preventing them from sitting low enough . when you push them down into place they tend to spring back over time .I have had much better luck with the Eddie's , I too use The Right Stuff thanks to the advice of OldKimmer and it works great .I have gotten away with using the blue felpro perma-torque units but they are not recommended for the Air Gap intakes.
