Sorry to hear about the engine damage.
But some food for thought, as $1200 is a lot of money to spend fixing your engine at the beginning of your journey.
Would it be better to go off on a 2 year journey with a known engine. Your engine repaired
Save some cash by picking up a used engine with No-Known history.
Hopefully you can find a good used engine with knowledge of its history.
I'd feel better with an engine, with a known history, when heading off into the World where parts and maintenance availability is limited, questionable or unknown.
Just my humble opinion.
