These rocker arms come from Hendrix motorsports and was used on one of their race cars. These particular rocker arms fit in SB2 race applications. They are an excellent shape and have all viable information printed upon the bottoms of them. Each cylinder is numbered with the intake and exhaust for which cylinder they came from. The rollers all look good and free of any chips or dings, that we can see. Great set to use or to display in your NASCAR collections. Thanks for looking and have a great day.
