Don't just tighten the bolts unless they need it!
If you didn't use a torque wrench when you installed the header, you could have over-torqued the bolts, which could warp the flanges. You could also end up shearing off one of your flange bolts and with an aluminum head... this is BAD!
Before you tighten anything, look around both your flanges and your collector for black, carbon scoring. This will point you where your leak is. Once you find the leak, replace that gasket with a new one, get a torque wrench and tighten it properly.
I'm not picking on you, just helping make sure you don't inadvertently make your problems bigger!
