the main difference between pedestal and stud is how they mount, pedestal essentially have a bolt that goes down through them and stud has, well a stud sticking up from the head that you put the rocker on and then hold in place with a nut. I've heard stud are stronger but I have no proof. Also I believe the way they adjust and are set up is different, I found my pedestal to be very easy. Just make sure you measure pushrod length.
If you have crane rockers and they're in good shape you can certainly use them, I don't think you'll see any power changes between rockers unless you go to a different ratio, ie 1.6 rockers to 1.7 rockers just because then you're opening the valve more.

It's the ratio.. 1.7 will add lift to what ever the cams original specs are.. Stick with the crane if you got them and want to stay with pedestal..

With the right pushrods they both are easy to adjust.. Anything from comp cams, scorpion is good..

there would be no problem using the rr you have now but if you want to change them you certainly can. I have no experience with stud mount rockers but the pedestal was cake, got the right pushrods, tightened them down, done.
