I'm going to be buying some cometic's next week. Which ones and which size do I need? I've seen the 3-layer ones on Thunder's website but I was told to get the 5-layer which I have not seen. This is going on an iron 5.3L bored out to 5.7L - 3.905" using 6.0L LQ9 heads. I'm gonna be running upwards to 20psi. Any help is greatly appreciated. I will be sure to use the copper gasket as well.

It says "copper spray-a-gasket" on the can. It also has a picture of a cylinder head and a gasket under the name. It's a copper based adhesive spray that is meant to be sprayed on gaskets to aid in sealing and help heat transfer. Specifically designed for Exaust manifolds, head gaskets, and turbo flanges.
