Re: Valve Spring Pressure - BBC stocker
If you indeed have 250# on the seat, and over 500# open, you have over 0.050" piston to valve clearance on the intake, and you have a valve control problem, then there is something terribly wrong. I can spin mine to over 8,000 RPM with those pressures, and a true 0.050" piston to valve clearance.
