intake manifold ?

[popsthebuilder]

Broke off the stud on the left side of the thermostat when I was trying to change it a few months ago. Tried vice grips. Drilled through and attempted screw extractor. Split stud. Broke off flush w/ manifold. Tried extractor again. Decided to tap stud. I was careful, and backed out the tap, and was using a small wrench as to not put excessive pressure. However I still managed to break the tap off nearly flush. I don't think there is any hope now, so my question is... Would an intake manifold off of a 307 of the same era bolt straight up to a 73 350? Also, would any 2 barrel work? Thanks in advance. Looking for the cheapest temporary fix.
