I have a 80 z 28 that seems to have coolant leaking down the side of the block. It is a 350 SBC with about 2K miles on it. the leak is very minor. It is coming from the around the center of the head/block side area where the two exhaust ports are for the headers.

The car runs well. Should I try torquing down the head bolts? What damage will it do if I leave it the way it is for now?

Thanks
