GM MLS vs Felpro MLS help

I'm trying to decide on which ones I need to run. I can't seem to find bore sizes or thickness for the Felpro MLS gaskets #26192-PT. It's a 2004 LQ4 block with 241 heads, a small cam and a 100 dry shot. Everyone says to run the GM MLS gaskets because they're cheaper and work great but I already have the Felpro MLS gaskets in my posession. Felpro says they have a blue layer/spray on them so they seal better. Any info on these Felpro MLS gaskets would be great.

The felpro 1 is fine its the same stock thickness and is made for the 6.0 blocks so it has the correct bore

The GM MLS gaskets have a coating on them as well. If it were me, between those two, I would go GM.

I've been hearing this throughout the years too and even though I want to run a Felpro to bump compression, I don't want to mess with something that doesn't have a consistent record. I prefer to sleep better at night and run the GM one.
