920 heads

Yep . driver side front corner by the bottom head bolt .
had a spare engine I purchased many years ago , went to switch over from 675 heads to the 920s and replace the cam too from the spare engine I fired it up and she was leaking anti freeze from that corner .
did not see the hair line crack until it started leaking.
we were thinking it had sat outside here in the winter time with water in the system.
