Exhaust Leak Help

[801coppertop]

So i just did a bunch of work over my spring break at school. Shifter bushings, guibo, CSB and such. So i obvioulsy had to drop the exhaust. I just pulled it apart not at the block but the bottom of the manifold. I did get new exhaust gaskets for this specific section, and new brass bolts. There on as tight as i can get them. Does anyone have any clever ideas on how to stop the leak?

Permatex copper RTV should do the trick. But pull it back apart first so you can smear a nice coat evenly on both sides of the gaskets.
