440 Header/Head Mounting Bolt

Radiator drained and no more coolant coming out of the lower radiator hose

Seems like the threads going into the head are still wet with coolant

Tried a few q-tips and some paper towels but I can't seem to get it fully dry

Will this be OK for the gasket maker and the stud to cure for a few days?

I also found a stud and nut for $3 locally
