OK, the best advice that I can truly give you is that you need to eat more then what you are currently. Now, I don't want to hear,"but I eat so much Mike that it's crazy, Mike you don't understand". The truth of the matter is that you still need to eat more. Your body burns everything in your system so there is usually nothing left to grab on to. You need to make sure your body has something to grab on to. - Mike Chang
Also you need to be hitting the gym while consuming all of these calorie. If you don't you will gain mostly fat.
-Train 4 times a week, don't worry about working out everyday. The reason is that your body probably has a very high metabolism so training everyday might not be needed right now.
-Make sure you train Heavy and do compound movements. Compound movement are exercises that uses 2 or more large muscle groups. The reason for his is that it will force the body to create mainly muscles with the extra amount of calories you are consuming.
