That 1/10th of an inch extra stroke should have pistons above deck with stock rods and stock pistons.
How was oil clearance on the rod bearings measured? And did the top half of the bearings get inspected?
The throws with .005" oil clearance are a bit much.
Given your location and engine temp problems... I would do some serious homework on SCR and DCR before running that cam advanced more than what's ground in.
And there's more

We did not measure from the center of the Crank to the top of the Deck; however, the piston is flat in the center and we used a straight edge bolted down and placed a feeler gauge in between the TDC of the number one-cylinder Piston and found 0.035". This is from memory, when My roommate comes home, I will ask him, I am thinking a little more than that. So, the Piston is not past the Deck for sure. We are performing a cooling mod. while the Heads are off, theoretically netting us 10 - 30 degrees cooler, we will see. Here is the Oil Temp. results:
RPM 190 degrees 220 degrees
500 20 psi 15 psi
700 20 psi 15 psi
900 25 psi 20 psi
1000 25 psi 20 psi
1500 30 psi 25 psi
2000 35 psi 30 psi

Considering this a stock motor, my roommate took measurements the best way he could, at the time. The rods are stock length.
Note: The Deck is not cut down, we know this because we can read the Piston letter code on each of the eight cylinders.
