Howdy,

As I don't know what your particular cam and rockers look like....it would be kinda hard to diagnose.....however, any valve train that has way too much clearance will damage both the camshaft and the rocker/follower.....as the cam turns excessive clearance will allow the rocker/follower to bounce and will eventually deform/dent the camshaft and/or the rocker.....once this process begins, it's too late to correct it....replacement with a new/used camshaft and rockers....or in larger engines with way more expensive parts, there is a spray welding process, and the camshaft can be reground from there.
