Pasta digests quite quickly. Your blood sugar will be high one to two hours after the meal. If your muscles are already topped up on carbs it won't do any good to wait for total digestion, unless you get a sloshy stomach that needs time to settle but that is personal.
Muscles hold a certain amount of glycogen(muscle sugar), once full they're full, everything else turns into fat. There are ways to superload your muscles and get them filled above the normal 100% mark but eating the morning of is not one of them. Also, muscles cannot rapidly use blood sugar(glucose), this is a safety feature to protect the brain which runs on nothing but blood sugar. Blood glucose is used by muscles, even when they have glycogen, but it is not fully available for maximal fueling the way glycogen is.
Your muscles actually store about a 400 grams of glycogen on a normal basis, or 1,600 Calories.
