My ac compressor makes a similar noise when turned on, but it seems you found your problem. If you are looking for a new engine, ebay has them for around $1000.

Possibly the engine ingested the dreaded steel ball from the PCV system and it pounded the spark plug.

A borescope might tell you a lot about what happened in there.

If you decide to fix it and you decide to try the head repair route….

No point in wasting time with bore scopes. Do the Queens Bidding!
