Screwup after screwup... what to do?

Thank you SO much guys... The crack is on the neck facing towards the cylinder head. I will just run it as-is for now and see how it goes. I feel like it won't be able to be welded for the same reason I had to grind it down before, the extra material will hit the head and keep the manifold from seating properly on the flange.

I was considering getting a set of cheapo headers but I don't have any experience with them and I figured they would be more of a pain to install. I'll probably do that after I move the car up to Denver and find a place to store and work on it.

EDIT: SirDan I didn't read through the whole thread on those shorty headers but it doesn't look like they'll fit with power steering which is what I have... what ones do you guys know will fit with PS?
