Problems with running solid roller cam valve springs

[JBeezy53]

I have GT40Ps with 1.7 roller rockers and TFS Stage 1 cam. I have these new Comp 914 springs laying around and was wondering what problems I would run into if used them together. I would also use hardened push rods of course. Will this set up cause collapsed lifters, bend pushrods or valves?

Here are the spring specs:

Recommended Camshaft Style Roller solid
Installed Height (in) 1.800 in.
Seat Pressure at Installed Height (lbs) 165 lbs.
Open Height (in) 1.200 in.
Open Pressure (lbs) 385 lbs.

They may be too stiff for the hydrolic lifters, may collapse them.

you need springs with lower pressures, they will probably collapse the lifters before the spring compresses.

Thats what I was thinking, thanks for confirming.
