JB weld is amazing stuff. I used it to fill in a threaded hole that retains the timing cover of my 1992 Taurus because I broke off a mounting bolt in and drilled in an angle, bad thing.
I filled the hole with JB weld, covered it up with masking tape and waited a day for it to harden. Next day I mounted the timeing cover, used a drill bit long enough to go through the timing cover and into the engine block, tapped the hole for a couple of Helicoil inserts after removing the timing cover, job was done and holding.
If you can, use the thermostat housing as a guide to drill into the intake manifold, it'll help you stay straight. You may have to buy a Helicoil kit of it but it's worth it. Better than paying for a new or even used intake manifold and all the other work involved to replace it.
