These 11 rockers are the High Performance BBC for engines cam lift in the .600 range. "H" stamped rockers replaced these late in 1969 and carried through 1974. These are used with little wear. Being rockers from the late 60's, most folks familiar with these will tell you they have a higher carbon steel hardness then the junk they sell today.

Priced to sell w/ 11 nuts and washers.
