It's got to be a combination of frustrating and encouraging to get a good dyno sheet but know that a whole bunch of power was left on the table with a simple adjustment.

No its not, unless he wants problems. Rod bearings, head gasket ect.
First pic is a KRE High Port with modern heart shaped fast burn chambers. They recommend 28-32 deg timing.
Next pic is the Speedmaster head. Almost identical.
The new Edelbrock CNC chambers are very similar.
The old Edelbrock bathtub/wedge chambers can use 36-38 deg timing. Some guys even run 42, but I wouldn't.
