This is among the reasons why EVs will eventually take over mechanically complex ICE vehicles. You've sunk a lot of time into the problem, and there's no guarantee that it will work well or last a long time after you get it back together.

I just spent like 2hrs trying to replace a battery in my Mom's $150 Nexus 6p phone, only to break the digitizer in the process. $80 later and another 2hrs spent, and the stinkin thing still doesn't work. I bought her a nice Pixel XL for $115 on Ebay. I wasted my time and money on something that was old and difficult to repair when I could have just moved on sooner.

If it were me, I'd take it to a shop to machine the head. Achieving smoothness is way to easy to mess up because sanding can cause a cheese grater effect where the areas toward the bottom of the direction of sanding receive more pressure than other areas and wear down quicker.

I have no experience rebuilding engines or fixing gasket leaks, but it seems like one of those things where experience really helps. There's head bolt torques that are super critical, and retorquing, and torquing in the correct order, and using the correct grade of bolt...
