Do I need to consume a decent amount of fat when trying to build muscle?

Ill be getting my fats in from eggs, milk, nuts, natural peanut butter, flaxseed oil, and olive oil (other than the trace amounts in lowfat cottage cheese and whole wheat bread and what not). So is it critical that I consume maybe around 80-85 grams of fat each day (I'm a 22 yr old, 6'3 and 163 pounds male) I already got my protein and my carbs down as i know they are important, just need to know about fat.
