Now that the heads are one we can go ahead and add the Livernois Motorsports Powerstorm Rocker Arm Base
. This base is available for both stock and ARP hardware. They are also available for all LS series engines LS1 - LS2 - LS3 - LS6 - LS76 - LS9 - LSA -LQ9.
These will help improve valvetrain and rocker arm control. With added spring pressures and larger camshafts the load imposed on the factory OE rocker stand and bolts often allows for flex and distortion. This translates into lost valve motion as the rocker arm deflects on the stand. These stands offer increased rigidity to keep rocker motion more true, and the added clamping load from the upgraded bolt helps to prevent rocker shift at higher loads.
