Any valves broke? Bent? Contact the piston? Looks like cheesy stock litters by the looks of that wire retainer. What pushrods? Springs are double? Single? Beehive? There's a reason behind this failure and I'm anxious to know. What was the rev limit set at? 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.
