My thinking was the shims to seat the spring and valve. No matter how much you shim the spring @ 800lbs. the spring is going to take 800lbs to start to open it. If the spring is Weak or soft the you loose lifting weight. Could drop to 600lbs.? I don't have that setup and I actually printed this in 2009. Things was really hard to come by for info then. If I did have it all digital on file I would have posted it. Scanned those pages
