Yes some will be lost but not much. How close of a gap is there?

ok, I was jsut worried that maybe it would break something or I dont even know.
I have chromemoly pushrods so they shouldnt bend or anything.
Hope I dont loose too much from it
and I hope its not too much of a pain in the *** to change the springs while the heads are on the car.

Power lost from strong valvesprings is "0". For every spring exerting pressure on the opening ramp, there is one exerting near equal pressure on a closing ramp. It is a regenerative system.
A hydraulic cam can take some high spring pressures. You have to watch oil viscosity and pressure though, cause these two can cause some pump-up problems. Generally, a strong spring only helps things but too much spring can also increase cam and lifter wear. "Too much" is a relative word though. How much open and closed pressure are you talking here?

I dont know how much pressure, how can I find out?
they are the crane dual springs, pn 99893-16

Alrighty then, I can probably get you an answer with a little homework (not familiar with that spring) but have you thought about calling Crane and talking with them?
I'll get back with you....
