I ran the high pressure spring in my forged bottom end stroker and hold 50-55psi warm idle, and 75-80psi at high rpms....
Since you have a stock bottom end you would probably went to run the lighter spring. Use the "o" ring that matches the old one in your engine

What were your bearings set at?

Honestly I can't remember, I had all the paperwork from the machine shop, but couldn't begin to guess where it might be. I took the shortblock to the machine sho and had him bore it over to 4.030", hone, turn the crank 10/10, new piston and rings , replace a rod, align bore, balance, setup and assemble with new cam, crank and rod bearings. I ported the heads, then had him milled them down to 57cc, and valve job....then I put the cam in and degreed it and bolted everything back together.
The biggest thing is finding a machine shop that knows these motors because they are not like the old sbc.....and yes he has a torque plate
