Valve springs will be the last thing to burn up from lack of oil....
I ran spring pressures, near 800lbs open pressure. IMO I don't see a bunch of extra heat coming off the valve springs due to more spring pressure. If anything gets burnt up, it will be the little parts in the top, push rod cups, adjusters etc. I know personally 4-5 guys running the Jesel stuff with zero problems besides me. Just stating my experiences..
