you need to make sure though that you are getting good sources of whole foods through the day as well. since the whey is quickly absorbed.. it leaves your muscles hungry shortly after using.. this will cause your body to start dropping into a state of a negative nitrogen balance and will become more catabolic. chicken, fish, eggs are great options and take a few hours to digest. this is why you want to eat every 2-3 hours so you keep your muscles full and in a positve nitrogen balance.
like i said in the previous post tho, your body can only digest and use so much protein so that is not the only factor into growing. carbs and fat are key as well. you want to eat a steady supply of complex and and high fiber carbs through out the day. the protein will build the muscle but the carbs will give your body the access to add more. if you are trying to grow, the more the better just start cutting them out later in the day so you dont have to worry about fat storage.
for growing it is said you want to consume at least 1 gram of protein minimum for every pound you weigh, and 2 grams of carbs. i like to eat for the size i want to be, not the size i currently am.
will will want to make sure you are consuming plenty of healthy fats. all 3 macro nutrients are important for growth. you can learn to manipulate the times you consume this.. like pre and post workout as you go, to better increase your results
