The STOCK Motor Parts do not have replaceable Cam Bearings.
Both the 350 & the 360 are the same design concept, but slightly different IE: Not interchangeable.
On both Motors the Cam Bearings are separate parts (End Caps) that fit into the side of the Upper Rocker Case.
While you can replace the entire End Cap there is not a replaceable bearing.
There are some who have done extensive machine shop surgery on the end caps to create a replaceable bearing.
To do so requires access to a machine shop and the skills to operate the tools.
