If a valve floated, it might have smacked a piston and bent a valve or put a small hole in the piston.
The oil pumps also don't like RPM greater than ~8,000 and since your clutch exploded, you were probably around 10-13,000 RPM or more.
You are lucky your oil pump didn't shatter!

Thanks for the ideas. I was planning on doing a compression test but I had been just out of sorts for the past 24-48 hours....but I can safely say, not a compression problem. Cold compression test came out 243, 240, 240, 240, 245, 241. Although my spark plugs were just slightly tight in there and that peaked my curiosity a bit as if the pressure backed them off some or they vibrated loose as if 1/2 turn past snug was not enough after I changed them about 2 weeks ago.

As far as oil pressure/temps go, I do not have an oil pressure tester and it appears they stopped with oil pressure from the switch to 370 from 350...but I have driven the car some prior to the compression test today and in 95+ degree heat in Texas and me pushing the car as hard as I could to test it after my clutch rebuild, it is not getting hot, staying between 185 and 200 max.

Any more thoughts before I just drop it at HoustonZ and pay to have them diganose/fix it?

P.S. Since posting originally and driving some, it seems to be producing decent power, just sluggish in comparison to what it was pre incident and changes in repair. like I said it wants to idle around 800-900ish now and from a start I have to rev it to about 1500-2000 to keep it from bogging and then it will actually spin the tire(s) [open diff still lol] some and it will chirp the tires in second, which is of course way less than pre-incident.
