Well I tried putting some ARP sealant and running the bolt back in.....done this twice to try and seal it. I went ahead and pulled the headers back off and took the helicols out and going to put some keyserts (I'm not sure why they are called that, but I think they are way better that helicols).

Drill a 29/64 hole for the 1/2-13(which is the thin wall kind) to go back to the 3/8-16 bolt. If it isn't one thing it's another.
