I have a set of barely used Pro Magnum Full Roller Rockers for sale, with the posi-locks. I put these on about a month before I pulled my motor out to build my stroker motor. They are part# 249-1330-16 (7/16 stud) for the 460 & not BBC. Might have 500 miles on them. Asking $200 shipped. They're $289 or $299 from Jegs, can't remember off hand.
