If you want to do it the right way...the permanent way, take the intake/exhaust combo off and have it machined at a automotive machine shop. The very least I would try is to loosen up the bolts holding the manifolds together at the heat box, reassemble the manifolds (with alignment rings),then after they were cinched down to the head, tighten the four bolts where they fasten together in the heat box.
