Made a little boo boo

I had a spare center iron I'm using for a cheap experimental motor. So when it comes to experimenting, I was pushing the limits of the porting. I actually ported the bottom edge of the bridge port deep enough to create a small hole into the coolant passage. The hole is maybe a 1/6" of an inch around.

I want to know if i can just JB weld it shut (as i was planning on JB welding a few areas anyways for better transition). This is an NA motor and will not see boost. I know that JB weld will withstand the heat, but will it keep the water from seeping in under pressure? How much pressure do the coolant passages actually see? I don't imagine it being much...
