The rocker manufacturers expect people to run crazy spring pressures and crazy ramp rates on the cam profiles with stainless performance rockers...they are meant to withstand significant abuse. You'll find the bearings are bigger/better and tighter tolerance than in most cases.

If you use these in a relatively mild combo, it won't be the weak link. Be careful of some of the cheap brands...they are look-alikes and have inferior bearings and bad finish work.

If you do intend to use a girdle, make sure you use ARP studs and make sure you TELL ARP you are using a girdle...or source the girdle and the studs from the same supplier. The studs otherwise will not necessarily be perfectly concentric relative to the threads where they engage the block; and if they are not...the girdle will not fit.
