Yeah, the clue should have been when you mentioned the set-up for bridged pivot heads since the bridged rockers already exist. This sounds like a cool idea which should reduce friction and stabilize the valve actuators. Steve Shaft rockers Date: Thursday, August 11, 2005 11:41 PM From: Andre K Jacobs <akjamc@xxxxxxxx> Steve These are a continuos shaft. FRANK, come on, the rockers you are talking about have been out a few years now, and are for the BRIDGED PIVOT heads. These are NEW for the individual stud head. They are also making a continuos shaft set up for the bridged heads, which will be better, and stronger then the current pair set up they have. The off set rocker is used when you move a port in a head, making in necessary to move the push rod. Andre " A.J."
