Always lots of questions as to which head gasket. And the usual GM MLS etc apply. Given cost and how effective they are, it makes perfect sense.

But from a technical standpoint. Which is better if any, and why ?

Cometic, GM, other ? 3 layer, 5 layer ?

Ive some TFS packaged gaskets here too, which I think are just 3 layer Cometics.

GM 3 layers made in Germany and 5 layer GM made in Canada.

The GM gaskets also have a slight coating, I assume this is to assist waterway sealing. So surely this is worth having over a different brand ?

For boost it looks like it's hard to beat the 7 layer LS9 gasket. I was extremely impressed with mine when they came in. $80 to my door.
