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 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 Mr.Cab Racing and winning with Mopars since 1964.

As you know, I am having trouble getting this combo to perform to its full potential and have started looking for reason as to why. I will be talking to the cam manufacturer today to get their opinion. Thanks.

If the 285/290 that you have stated is actually at 0.020" (verses the .20" you state) then that is a pretty aggressive lobe and would think you would need something like the 943. (250/650 ish) spring
