The problem with used performance heads is the same as the one with used factory heads - you don't know what they've been thru, and what work they'll need. They may have very well been put thru hell and not show much of any indication of it, especially if you're buying them online and having them shipped.
Most aftermarket heads do come with 3/8" studs already, guide plates included usually. It's a much nicer setup than the pedestal mount, stronger too. PEdestal is great for factory setup tho... Tell you what is a stupid setup, GM's pressed-in studs.
