Are heavier valve springs better?
Higher spring rates mean greater force on the camshaft and consequently more resistance to rotation. The flip side to this argument is that stiffer valve springs control the valves better at high speed and provide better prevention of bouncing valves, which can create more power.
What do bigger valve springs do?
In a serious valvetrain, anything more than 0.150 inch can cause spring surge, which can greatly reduce the available spring load needed to close the valve. The distance from the retainer to the valve seal must also be greater than the valve lift.
Can you have too much valve spring pressure?
Yes, too much spring pressure will damage parts. As you have seen first hand. Too much seat pressure will collapse lifters and cause valves to float as well.
