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 stock "slotted" pushrod hole drilled out to a round hole. Cannot be used with guide plates.
