Better be sure it was not a slipped valve guide which caused the problem rather than stuck valve, much more typical. IF you find that, post back for fix.

To bad, I have a tried and proven fix which only costs a head gasket.

I have one with a slipped guide and just have never had a chance to fix it so what is you tried and proven fix. If you would share I would appreciate it.

My narrative includes alternate fixes furnished to me by others with permission to share including a variation to mine which does not even need a head gasket. So, too long to post here. Address below, put in proper format and remind me what you want.
