I am working on new 140 heads, and I have to put in new studs. I can go to the local hardware store and get threaded rod, but should I be looking for a coated metal, or a stainless? Even a coated will rust where I cut it, but I can paint the exposed areas. Should the studs be set in loctite? Tom Wright St.Catharines www.vaxxine.com/tomspage 66 Corsa 140 Corsa Ontario CORSA
