"Replaced exhaust manifold and
"Replaced exhaust manifold and found bad corrosion on #4 exhaust port on head. Is there any fix for this other than replacement? I heard of a steel sleeve insert but am not sure if this is factory or aftermarket.
Also, is there any chance a head from a 1988 230A engine will work on a 1979 AQ120B? I know the exhaust manifold, valves, ignition and fuel systems are the same or similar, while short block parts aren't. Head and Valve cover gaskets are not the same. Casting mark on 230A head is 1000531 while mark on AQ120B is 1000160.
Any help with this would be appreciated.
Thanks"
