The Dormans I have seen have plastic screw holes for the COP's. If you overtighten one time...blah. The Ford OEM has brass sleeves for the COP screws.
Need Some Help!!! - Coolant Leak

From a past dorman intake user they are junk, not only did my lower intake fail at the typical spot faster than the ford racing pi manifold (stock), but the manifold cracked causing a massive vacuum leak. And to top it off the car didn't feel right until i put a ford manifold back on. The manifold was used primarily in Phoenix so temps may have come into play...
