Manifold to head exhaust leak

Manifold to head exhaust leak
I've got an exhaust leak off of runner #1 and I'm just wondering what is causing it/how to fix.
I used a new gasket and Permstex Ultra Copper sealant. It was good for a few months. Then after some hard pulls it started leaking. I pulled it off, replaced all the studs and nuts, used a new gasket no sealant this time. It was leaking right away. The manifold is welded els, all mild steel.
Do I need relief cuts? Do I need to get it milled? ( anyone know a price/and place around Chicago? ) Different gaskets? (I'm using stock)
I attached a pic of my mani and marked where it's leaking

RTV is not useful on an exhaust manifold.
