What would cause failure
Yeah Brian at Aes didn't send pics of pistons but most damage was done to 1 head and the valves waiting to hear back from him if anything else was wrong. Ill update once I hear back from him just been so aggrevated with all that has happened with car and its not been just the engine damage either.
I feel like the plug and timing wouldn't of done this had the fuel system been set-up properly.
Fix the way the fuel is fed to the rails, and you will be a happy customer. That said, try it with a little less timing, or put one step colder plug in it.

Thanks Martin and everyone else with helping diagnose the issue I'm not good at tuning.
I fought the shop will help out much but we will see, I just hope things go smoother this time around.

Got an update need 4 pistons and new valves and valve guides for head
Also think we found the issue, they only fed 1 rail not both and that's why only one side hade damage so will be addressing the fuel issue and hopefully fix everything and maybe go even faster once all is done.

They ran fl to regulator to one rail and fed to other rail instead of running fl to reg to y and feed both rails this is what we feel caused the issue and damage to one side and not the other.
And yes it should be trapping in the 149-155mph range so I think it was starving for fuel and thus making less hp. Ill post when I get more.
As for the shop I really haven't said much as they have not said any plans because not sure what happened until engine was gone thru but hopefully they can help me get things corrected and finally get to have real fun with the car.

Stevie, sounds like they ran from the fuel pump into one inlet of the regulator, then connected the other inlet of the regulator to one end of the driver side rail, then the other end of the driver side rail to one end of the passenger side rail, then the other end of the passenger side rail capped.
It'll run like that up until you get to about 75-80% of your pump capacity. Then your end rail will have more pressure while the middle rail starts bleeding off before the regulator can pinch it off.
They should've gone pump to y to ends of both rails, then each rail end to the two regulator inputs. Or worst case pump to T at one regulator input and then to rails with the other regulator input capped. Wouldn't risk it on a boosted car though.

As for why it might have been down on power, quite possibly unless they were taking measurements on both banks of cylinders and not just one or combined. If one side was running lean and the other fat, could definitely be down on power.
