Head Gasket experts...check in....

These gaskets look very familiar to me..........

First question: Is there any signs of detonation on the piston crowns? It is a "maybe" possibility cause
Second question: Is there any evidence of water in the chamber? A drop of water vaporized during combustion can/will raise cylinder pressure high enough to blow gasket out. It is another "maybe" cause.
Third question: Are all the chambers bulged towards the valley? By the pics it looks as though they are.
Fourth question: How does your intake fit? I will guess at the moment (please correct me if I guess wrong ) you use a bead of silicone to seal the intake to the china walls; does it remain a robust bead or does it all get squished out?
Fifth question: How far was the block decked? As in what is the measurement from the crank center line to top of deck?
