Stuck guides are a common problem too . I once owned the special tool for hitting the split valve guides out from above .

It's a length of rod bent to fit around the valve head . A section of the rod is machined/ hollowed out to form a tube , this allows it to slide down the valve stem .

You slide the tool under the valve head onto the stem and down on top of the guide . You can now hit the tool head and the split guide comes out .

Ryans in Melbourne sold these special V8 tools in the 1950's and 60's .

There was also a bar for levering the guide and removing the spring clip .......

I know who has the tool, and I can get it back if anyone needs it .
