I would buy CDS's 5K's and be done with it. Stud protrusion is the least of your worries time and time again has it been stated that u set your gov springs by clicks irregardless of stud protrusion, it is a balanced assembly.

The CDS springs idle smooth as silk, as did the early version of the Scheids
5k but thier later version had a wild ass lope that made it sound like a 1500hp Mod Pull truck...the only prob. with them is they wouldnt pull the rpm I needed even when tight? The CDS's will.
