Default Exhaust manifold gasket question

Does the steel side of the gasket go against the block or the manifold? TIA

heat expansion is the reasoning behind this gasket design. Breaking it down, the manifold would expand and slip outwards as it "grows". The bolt holes on the manifold are slotted for this reason, although the holes in the gasket are not slotted. The fiber side is meant to keep it held in place, the metal side to allow slippage. My thought, if it grips to the manifold with no room on the bolt holes, it would rip, or atleast warp the gasket. My vote is metal side to the manifold.

well... I just did mine... and it was never removed before... factory assy
and the ring was toward the head... metal toward manifold.

And the above reasoning makes sense... good explanation
I also read somewhere here the same thing

Steel (shiny material) towards the cylinder head!

Verified this with Lindsey Racing and Zims Autotechnic

Don't mean to question the gods, but every other engine has had the like like metals together. Fiber towards the alum head, metal towards the manifold.

Just put together an engine together....metal towards the manifold.

Did Dave give any explanation?
