the same thing happen to me last year, i had replaced the head gasket twice and even went back to my stock heads, didnt help, ended up having a hair line crack between the cylinder wall and the water jacket. i was told it can be fix but i found a ls6 block for a deal so i went to that.

same thing just happened to me on my stock ls1 i had an sts kit on piston broke in almost the same place and my wall had a huge crack from top to bottom on the side where the water jacket is.

Did you ever notice a leak before this happened? Is it possible your coolant was low and you never noticed? It is possible that the leak, (crack or pin hole), happened after the detonation and damage to your motor from the intense heat. It is also possible that the leak had let enough coolant to escape to cause the detonation and destroy those cylinders. Hopefully, your mechanic can diagnos the problem so it does not happen to your new motor, such as fittings, hoses, heater core etc.. My point is, look for the inobvious just in case. We have found the damndest things at our shop over the years. Hopefully it is something obvious and you can put this behind you. Good Luck on the 427.

I read in the FI, and even the tuners are in consensus that it is an intake issue.

Isn't a result of the intake, and the tune with having too much air and not enough fuel?

Damn dude, sucks to hear about your motor. Goat's tranny blew, so I feel your pain.
