The new 363-3731 Valve Bridge is now available as an optional service replacement of the existing valve bridge on the serial numbers listed above.
The new valve bridge is thinner than the existing and does not have a notch cut in the bottom of the bridge. The new bridges allow for more clearance to set the clearances on the cylinder head valves.
