Header Leak??

Oddly enough its my number 1 cylinder as well, when I first noticed the leak I could see there was a separation, and the bolts were almost to the point I could turn them by hand.

And I never actually torqued them, I just tightened them by hand with a wrench, so some may be tighter than others. I will torque the ones I can down after I replace the gasket, hopefully that helps provide even clamping force and I don't get any more leaks!
