Ok update for you guys, upon further inspection I have updated pics for you to make a an informed decision.
It appears that lower bolt hole was attempted to be threaded.
Also I've attached a Pic of the hole that was made and I think it's a cooling passage. The bolt I removed showed no oil residue and just smelled like coolant and visually showed old coolant stains
