340 with 302 cast head for pickup

Oh, I also looked at the "advanced" version...to be honest, the amount of material removed from the deck or from the heads is irrelevant once you input the piston to deck measurement, and combustion chamber volume. Also, the basic version on the link you provided does not include the head gasket diameter, piston to wall clearance, or first piston ring measurement...I suspect the calculator assumes gaskets the same or some "set" amount larger than bore diameter which is rarely the case, and possibly a theoretical zero for the other two measurements, which is also in error...both of those measurements will lower the number when compared to a zero measurement...
