I am trying to take off the heads on my stang and i was hoping the be able to take them offf by just unscrewing the exhaust manifold from the head but there are those stupid bolts under the exhaust manifold that I have to take off. So how do you get to the screws where the exhaust manifolds meets the pipe? It seems like the cats are in the way. Should I go from the top or bottom? It also looks like Ill need to use a ratchet because there is a little lip on the connection part.
