I figured it had to be over-boosting, I wonder why it blew at 17#s, I figured with the quality heads and studs it could handle more, makes me second guess my decision on my getting the edelbrocks for my motor. Stock castings have made it to 16#s multiple times with no problems.
I think 17 psi and detonation might have had something to do with it. I am running 12-13 psi without any issues at all. I plan on running 14-15 with the 1900TVS here soon.

Hey Julien. Sorry to see the trucks down, but it's in good hands with Rick and the Synergy crew.
The "pop" you heard when the boost spiked was a lean backfire that occurs in the intake. My old turbo Triumph would do it all the time with the draw through carb in front of the turbo. One time it happened to me on the Marina del Rey fwy at over 100mph. It scared the crap out of me. I thought I blew the engine up but I didn't see any smoke or parts following me. The backfire blew the carb off the front of the turbo and I coasted to a stop, so I climbed out and re attached it and continued on my merry way. Sounds like you found the same problem unfortunately it cost you a head gasket. But better a head gasket than a piston............ The head gasket makes a nice safety fuse. The guys with the 6 bolt blocks won't have the luxury of a safety fuse.

The head gaskets acting like a fuse is nothing new to some Ford customers of mine. They also have a 4 bolt head pattern.
We put some real high quality parts into that engine. They're holding up as designed. I'm happy to see the "rock" will still be rolling.
I like your sig...........
