Question pertaining to exhaust manifold gasket

[Xdt]

Hello,
In the process of installing exhaust manifold gasket purchased from Jerry's Gasket. The gasket has a metal layer covered by a paper backing on both sides. One side of the gasket is textured and has more paper element covering the metal. The other side is more smooth however, the paper element covering the metal is not as thick.

Question: Which side faces exhaust manifold?
The thicker textured side or thin smooth?

Thank you in advance
