Engine start up precautions after overheat?

[samwise68]

alright,

so, as some of you know, my dad and truck had a bit of an accident involving a tree.

after getting it out of the snowbank, we drove it home. but, the bottom outlet on the radiator had pulled out of the radiator itself. needless to say, the temp idiot light was the one calling me an idiot.

we only drove it about a mile, parked it in the garage, and that was that.

this weekend, the plan is to put another radiator in it, and start it up again.

i was wondering if there was anything you would do as a precaution before starting it up?

it's a 307, 2 bbl, and headers, if that makes a difference.

i was thinking a thing of Slick 50, might help? or some other additive?

just hoping for some insight.

thanks in advance!
