Cam bearing problem

Machine shop here wants $400 to hot tank and cam bearing, and install a $5 set of core plugs their charging $25 for. Seems steep for a bone stock rebuild

I think it is. I had a 340 sleeved for that and the price included one sleeve, boring and honing the sleeve to match, labor, hot tank, cam bearings and core plugs for that same $400, and people told me that I got ripped off.
