Head Question

Heres why I ask. I just bolted on a set of 302 heads and on to those I bolted a set of Spitfire headers with no gaskets and not really bolted on real tight. I bolted the Spitfires on to burn off the paint they had from shipping so I could then remove them and paint them with a heat paint. Well when I started motor I saw antifreeze leaking from front end and rear end where header is bolted. Do you think it is because I didn't have header gasket and didn't have bolts pulled up real tight, or something else? Thanks Mike
