Zezus

Okay Boys, so I done screwed the pooch on this one.
While installing my art pipes, i broke off the stud in the drivers side exhaust manifold (at the 3 bolt flange)
I was already pissed at the project at the time so i just slapped everything back together.
Obviously, I now have an exhaust leak.

So I now have 3 options:

1) Replace the factory manifolds with shorties (I was thinking Z1)

2) Remove the factory manifold and drill out the f*cked stud

3) Say f*ck it all and buy longtubes and sell the art pipes.

I was leaning towards option 1 but I know there was a redesign of the header in the late models. I'm not sure if going the shorty route is even worth the trouble.

I did try to search but i can't find anything other than "shorty bad, long tube good" without anything to back it up.

Advice? Opinions? I'll even accept name calling.
