Product Description
LS3 intake Rocker Arm Conversion Kit with Billet Stands
Kit includes:
QTY 8 new Genuine GM LS3 Rocker Arms
QTY 2 Michigan Motorsports Billet Rocker Arm Stands
DOES NOT include exhaust rocker arms
This kit is a great option for people converting from cathedral port to rectangle port LS3 821/823/5364 Head castings. These style heads use offset intake rocker arms and stands specific to these heads. This kit includes the intake rocker arms and stands. Your cathedral port/LS1 style rocker arms can be reused on the LS3 heads.
Included in this kit are Michigan Motorsports' billet LS rocker stands which are an excellent upgrade for your valvetrain. CNC Machined in the USA from 6061 Billet Aluminum, these stands offer improved rigidity and reduced flex compared to the OEM stands, as well as more consistent rocker saddle heights. The OEM GM stands can vary as much as .015", making it difficult to set consistent lifter preload heights especially when dealing with short travel aftermarket lifters. The rocker heights on these billet stands are true within .001" over their full length. Replaces GM # 12600936.
