valves

Figured id just make a new thread for this… Ive been looking around for a little bit now and i cant find any information on what shims i need for a 1980 cb750c custom I have yet to take out the old shims and check sizes so im not yet sure how thin i need the shims to be, but before i start...

So im trying to keep and do as much of the work on my 75 750f as possible to help keep cost down and stay with my budget. What's the steps and tools I need to do a valve job like the gaskets and redoing the edges for the valve seats its something I want to do along with the other engine gaskets...
