I would expect all three on that bank to have hit or showed that they hit but not necessarily all break. I'm not sure if it is possible only for on or two cylinders to show it.

Those anomalies are why I've been leaning more towards a head decking issue.

You should have th etime to measure the thickness of the head from the valve cover mating surface to the head gasket mating surface.

See if we can rustle up some specs on that thickness and of course the tolerance limit.

Maybe Procyon knows the stock head thickness before decking.
