The new wood should give you nice modern shooting dimensions.
Some things to consider. Your gun is of 1904 vintage. At that time the "standard" 20-gauge shell in North America was 2 1/2-inch. The heaviest loads offered in that 2 1/2-inch 20-gauge shell were 2 1/4-drams of bulk smokeless powder or 18-grains of dense smokeless powder such as Infallible or Ballistite pushing 7/8-ounce of shot. With Parker Bros. practice of holding chambers 1/8-inch shorter than the intended shell, unless they have been lengthened, the chambers were likely 2 3/8-inch when they left Meriden. I have a VH, 0-frame, 20-gauge of 1930 vintage and it has the 2 3/8-inch chambers.
1904 was long before beavertail forearms were a thing, so your gun likely does not have the reinforced forearm loop that Parker Bros. added when they began offering beavertail forearms.

A firm grip on a beavertail forearm puts a lot more strain on the forearm loop during recoil than a hand on the barrels over the tip of a slim forearm --
