I think you're kidding yourself if you want to run a .700+ lift solid roller on the street and not replace valvesprings. Tr
My pump gas Duster (.730 net lift on the intakes and .705 net lift on the exhaust valves) had over 3500 street miles and hundreds of passes at the track with no bad valve springs, I did shim them between .015 and .030 when I switch heads the last time to keep the seat and open pressures within 5 to 30. lbs. when I first put it together back when( between 2002/2004) The key is to use good valve springs to start with and make sure they get enough oil on them to keep them cool enough to not loose tension when driving or racing them
