Comp 932-16 springs, 513 lb. open pressure- 200 lb. installed pressure.
Camshaft is solid roller 621-624 lift- duration @.50 is 254-258.
Also using 1732-16 retainers, 4700-16 spring seat cups and 10 degree crower locks.
I wouldn't run those pressures on a solid roller cam today, step the pressues up to 250 Lbs + on the seat and shoot for .060 to .080 before coil bind at max lift, if that gives you 600 + lbs of open pressure then I might consider using them We really need to know more about the lobes though ![](/ubbthreads/images/graemlins/1343795-scratchchin.gif) I've learned the hard way that using a tiny bit to little valve spring pressure on the seats will wreak havoc with the valve train, especially the solid roller lifters ![](/ubbthreads/images/graemlins/shruggy.gif)

... I will be talking to the cam manufacturer today to get their opinion.
IMO, that's the first place you should have asked. Their grind, their spring rate guidance...
