problem found
pan is coming off already, because it is full of teeth from the crank timing sprocket. and also its nearly impossible to get the timing cover back on there with the oil pan gasket in the way

That is because the timing cover is made to go on before the pan. The pan seals to the cover.
As has been said, the entire motor needs a teardown after a catastrophic failure like that. It is catastrophic because of the fact it happened while at speed...
In all actuality something else bound up causing the cam gear to take sheer action. I have seen that happen when someone misses a shift and mechanically over-revs the motor. One guy did it twice, first time it sheered the bolts off the cam (yes the heads where trashed after that), and the second time it broke the chain and spit it out the side of the timing cover (what sucked about that one is because it was RIGHT after a complete rebuild with less than 3k miles on it)...
Any way you look at it, the only way you will be 100% sure is to tear the entire motor down. There could be bearing damage, rod damage, heads, valvetrain, etc...
Here is a pic of some bent rods from a motor that was still running (this was because of too much power on stock rods, to the tune of around 650rwhp, but the motor still ran with only a 1/2 engine tempo knock, which was one piston skirt hitting a counterweight only on the power stroke, and yes that one rod is bent on three axis):
So, just because everything 'looks' ok, or sounds 'ok', you won't know until you tear it all down...

well i pulled out the whole rotating assembly, had it inspected, and everything survived. I sent the heads back b/c the guy said might as well replace the valves to be on the safe side, and since the heads were off already. pulled the cam out too, just to check it out, and it looks ok still.
Yea, I could see that creating an issue!

I can't help ya on the cover, For Sale section maybe?
I guess the rest of the valvetrain/engine survived?

He would want 9-3145 for engines with a factory roller cam.
