These 302/351W Small Block Ford aluminum rocker arms are 100% CNC machined from the finest materials. Needle bearing fulcrum, centerless ground trunion and heat treated to the proper rating. Polylocks are included.
Probably one of the best kept secrets...the best engine builders use break-in roller rocker arms. With the extreme valve spring pressures racers use today, the initial run time can kill a camshaft in the first minute of running. The big time engine builders use these 1.3:1 ratio rockers to allow a run-in time for the camshaft, then the 1.3:1 rockers are removed and the normal rockers are reinstalled and the engine is ready to race or dyno. Polylocks are included.

BluMax Small Block Chevy Aluminum Rockers are designed with strength and durability in mind. The rocker bodies feature a deeper relief to accommodate larger valve springs, and are designed with longer slots and specially designed pushrod cups, to take advantage of high lift camshafts and roller lifters without extensive modification. The BluMax self-aligning , narrow-body aluminum rollers are for use with center bolt valve cover heads. The narrower profile accommodates the later style Chevrolet engines with center bolt valve covers. Cannot be used on heads that have not had the ...
