When you say 'pulled out' Hugh, is the thread in the block stripped? (if in doubt, try gently screwing in a 1/4 BSF bolt and see if it holds).
If yes you have 2 basic options, helicoil the hole or drill & tap oversize. The latter is probably more robust. I wouldn't attempt it in the car though. I'm sure one of our suppliers can sort you out a stepped stud.
If there is a bit of thread left you can probably run around for a while without major consequences but you will need to address water leaks into the manifold most likely.
