LOL. I Thought I could fix this engine... then This Happened…!

I thought I could fix this GS… In this video, I finally start working on the engine, using advice from YouTube and the manual. The plan seemed simple.Get the engine to top dead centre and take it from there… but things didn’t go the way I expected. Halfway through stripping the cylinder head… I found something I wasn’t ready for. And now I’m sitting with a decision I honestly don’t have an answer for. If you’ve got advice or have dealt with something like this before, I’d really appreciate your input in the comments
