All your car manufacturers use multi layered steel gaskets. These help with detonation and the use of dissimilar metals.And also rotting out,or blowing out due to high compression,which all the car makers are running for emissions.

Default Felpro 7733PT2

Im wondering if 7733PT2 is teflon coated as i tried to find it online and cant seem to find it ?

People I trust told me to use Fel-Pro FE1010 head gaskets with aluminum heads. So that’s what I did and I haven’t had any problems.
If you are interested in calculating compression see below.
Gasket bore​​ 4.166”
Compressed Thickness​ 0.39”

They work, they are cheap, and reliable.
Buy them. You wont be sorry.
I agree. I've also used them on several L98s without issue.

Do they have copper combustion rings? I’ve heard the ones with the steel ring are ok for cast iron heads but will Brinell Aluminum Cylinder Heads.
