previous experience of doing the manifold(s) on my Driver is that to get to all of the bolts on the exhaust manifold, the inlet needs to be off!removing the carb is simple enough, disconnect everything either labelling it or remembering where it all goes!earths, vac pipes etc. and then the bolts in the bottom of it and lift it out and the inlet isn't too hard to do as nothing should be seized but actually finding the holes is sometimes tricky, you'll need a long allen key to reach them and then, once thats off you can get to the upper bolts on the exhaust mani and the bottom ones will need to be got at from under the car. All i can say is enjoy!hope this has helped!
