SD Pro Springs.........
Good to .600 lift
anyone had any experience with them? 118.00 bucs and 98 for Ti retainers.
Just wondered if they were comps in a different box like some pushrods that are sold!
, there installed in my new heads which im in the middle of installing right now. the springs are manleys and the tit. retainers are also manley. cant beat 178 for springs and tit. retainers.i havent heard anything bad about them, there replacing my rev duals.
