valve spring pressure

[turbojet427]

I am getting some conflicting stories with valve spring pressure. I'm running a .710 lift solid roller with mostly street driving, burnouts, and some track time. I don't plan on spinning this motor much more than 7,000-7,500 rpms. I'm being told to run a spring with roughly 250 seat and 700+ open pressure. I'm also being told to run roughly 200-250 seat and no more than 400 open pressure. I was also told to run a rev kit with the smaller spring pressure. I think the big open pressure would kill the valve trane on a street motor. Any opinions or success stories?

BTW the cam card has no specs for spring pressure. Its an older (but new) special grind cam.

Check with whatever manufacturer ground the cam.
