One pair of rocker arm assemblies for the Y Block Ford and Mercury, 1:54 ratio. Each set has been thoroughly gone through with cleaning, inspection, new rocker shafts, replacement rockers and bushings as needed, and resurfaced tips. The pair will ship in shrink wrap with installation instructions. 
 
Some of the rocker arms have been resurfaced and prepared by Rocker Arms Unlimited in Redding, California. Many others were fine and only needed their tips resurfaced.
 
Adjusters are not included; two-piece adjusters always recommended.
 
Note: Foreign purchases please inquire.
