I have an exhaust leak on my '79 400 4spd Trans Am. I took it to the shop and one of the studs on the exhaust manifold is broken so my mechanic said he would have to remove the exhaust manifold and drill it out. But he thinks the exhaust manifold bolts will break and then he would have to remove the head. The bolt on the exhaust looks fairly bad. Am I better off risking him trying to remove the manifold or should I just jump in and have the block removed and freshened up. The latter is $2300 and the former, who knows? Are the manifold bolts fairly weak? Any advice will be appreciated.
