    Thyy all crack there..WTF? Using header gaskets under them? Use the #72 Muggyweld stick. The swap meet ones they demonstrate on AL with a MAPP torch melt at 350F, far below what a manifold can see during a hard run/lean run or cool down.

    Got the repaired exhaust manifold back from Perkins Repair Services. Here are the photos:

    Looks like a good job to me, resurfaced all flanges.

      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.
