That will make it a lot easier to do the adjustment, but it requires removal of the cam I think, which is not something you are going to do in-frame.

Can't say I have ever had a problem with bent valve stems on a Ford.
I can see some hassles with doing a valve job then!

So how do shops grind the valves with their mushroom tips? The seat grinders I have seen chuck the valve stem.

And grinding seats in the block must require a tool that locates in the guide bore? Sounds specialized. And nasty if you spread grinding debris around the valley.
