Just an echo.. as far as I know ..it's the constant extreme seat load that can hurt a cast iron roller cam and not really so much the open of your average load requirement. Rock on!
I don't know you, but you call someone an "asswipe" and yet post this up ^.
You do know that the cam does not see "constant extreme seat load" right?
The only time the cam sees "seat load" is when it first opens the valve. When the valve is closed, the cam sees only pressure from the lifter plunger and oil pressure in a hydraulic cam. Perhaps the initial jolt of opening the valve against the spring's seat pressure is enough to wipe some lobes, but the lobes themselves are not under "constant" spring pressure or load.
I only point this out because I don't think you should be swearing at other people for no real reason.
