This is a New Old Stock set of 16 OEM GM high performance "H" marked rocker arms. These were used on factory Big Block Chevy applications with solid lifter camshafts. 1965-1968 Big block Chevy engines with solid lifter cams used X and L marked rocker arms. In 1969, the second design L88 received the revised "H" marked rocker and all solid lifter engines from 1969-on used the new "H" rocker. The "H" rocker also superseded all earlier high performance rockers. These OEM high lift rocker arms are very hard to find.  Don't miss this awesome set of 16 NOS GM "H" marked high performance rocker arms in the original boxes. 

These rockers are in excellent unused condition as shown. These are brand new in their original ancient GM aqua and black boxes. They really don't get nicer than this. 

I understand these are not cheap. NOS GM high performance parts do come with a price tag. I also have a very nice used set of these H rockers at half the price. I plan to get those listed soon. If you are interested and don't see them listed, feel free to reach out to me. 

This is your chance to own the real deal set of 16 New Old Stock GM "H" marked rocker arms you have been searching for at a GREAT PRICE. Don't Miss Out!
