Don't tear into it too deep yet. I agree with Peter Packard. The probelm is most likely the sticky #8 exh. valve hanging open causing the .030 clearence.

Try removeing the spark plug and snake oil the valve stem when valve is fully open. JUDICOUSLY use a small brass drift to see if u can LIGHTLY tap the valve closed when crank is correctly positioned. Usualy, on MOST Flat head engines the exh valve head is very near and under the sparking plug hole. I don't know if that is the case for Packard or not but it's a most common design.

Bottom line, i'd attempt to free up/UNstick the valve before any major disassembly.

The sticking exh. valve problem is becomming rather wide spreead among a variety of engines over the last 2 years.
