Use of PRC springs w/ stock cam? Some will raise an eyebrow and say I am doing twice the work but I have the springs now and still working on getting the right cam. Plus I have some spare time coming up. So, I figure since I am new at this I would take baby steps and do my springs first. Any harm in instaling the PRC springs and running a few heat cycles and then throwing in the cam when I get it? Thanks,
Jim K.

Thanks X,
I do have the hardened pushrods ready to go.

Possibly there will be a small power loss with the heavier valve springs (though I have read that the extra energy it takes to compress a heavier spring is then stored in that compressed spring and released when the spring opens which evens things out), but just how will the lifters be any more overworked with the stock cam vs. the aftermarket one when he gets it? Will the lifters be less worked when the aftermarket cam is installed?

The ramps will varie & therefore the rate. Sharp rate opens and closes faster applying said pressure for less time.
This in turn allows the lifter to keep more "pump-up" and that puts less stress on the lifter hydraulics.

No, what I'm saying is with heavy spring pressures and a slow ramp rate, the lifter has more time to bleed (due to more effort required to press valve open and the extra time it takes). When this happens the hydraulics have less "pump up" and more stress are on the lifter internals.
