I don't think or believe that the lifter weight has any bearing on how the valve springs act, live or wear
Dale Armstrong did ,allegedly, some engine dyno testing on weight on the lifter side of the rocker arms by adding weight onto the pushrods back in the early 1970s when he owned and operated 10,0000 RPM speed shop in SO CA on one of his blown alcohol Hemi motors. His conclusion was that the weight he added on the lifter side of the valve train had no measurable impact on the motors HP or where the motor made peak torque or peak HP
I was told by one of the better racer reps at Comp Cams 10 yrs ago that current hydraulic roller lifters where very sensitive to the valve spring pressures after having issues with their hydraulic roller lifters back then
I haven't used a hydraulic roller lifter cam or lifters since then, burnt once, twice shy
