Is This Exhaust Manifold Repairable?
Happy to see they resurfaced the whole thing. They are usually warped, and if that resurfacing isn't done they easily crack again when you bolt them down. Note, however, use the thickest gaskets you can find, because sometimes that funky outlet pipe hits on the head and you will really crack something due to the interference.
edit: I'd check to see if it is hitting now. You can always grind a little material off if it is.
