As always head gasket wise when you look at the percentage of failures it’s mostly from the heat of two center exh ports and there far faster rate of expansion and contraction ( sheering) of the gasket.

And often they use hat washers under the bolt head to make it work and any head gasket that doesnt have enough clamp load will fail first at the hottest thinnest point, but go ahead with that awesome logic
