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?

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.
