Unfortunately there's alot more to putting a cam in than just sliding it in and putting the recommended springs in. Geometry of the rocker arm must be correct. Installed height must be correct. Piston to valve clearance must be checked. Retainer to guide clearance checked. Coil bind. I hope your shop did all the correct installation precautions.
Do you see any pits on the piston top? They might be really really small.

So far, it appears that no valves or springs broke. I know for sure the intake valve on # 1 is bent...I can see that through the port. Pushrods are from Trick Flow ( 7.400 pushrods ) Springs are dual Patriot Gold LSx kit. I have to verify the exact RPM of the limiter. The car ran perfect from the time the cam was installed 9/2/10 till destruction day 6/10/11.
Haven't pulled the heads yet...stay tuned.
