proform roller rockers

a lucky rabits foot, a 4 leaf clover, a horse shoe, and cross your fingers.lol

be careful with those, I hear the adjusters break, so maybe get some harland sharp adjusters for them like I did for my off brand aluminum rockers.

Check spring to rocker clearance, make sure you have 2 threads above the lock nuts when lash is set otherwise look into diff length push rods, and keep an eye on'em for the 1st week.
