New Here, New Build

Sup guys, new here. I'm 34 now, bought my first stang in high school... 87 gt, still have her. More recently I bought an 88 gt, same car but the 88 is auto with 70 k. Recently I've acquired a set of trick flow 11r aluminum heads. Is anybody running those or does anyone know what kind of other mods I will need to do? The motor is a factory 5.0HO EFI WITH 70k mi. I am going to pull an explorer intake Tuesday from the junk yard. Bare with me, I'm a noob and no more than a magazine mechanic so questions will be asked in abundance.
Thanks for your time,
Mario88

Thanks guys!
So...I pulled an intake from a 96-97 explorer, I want to throw a 70-75mm throttle body, do you know which will fit? Will any aftermarket throttle body for gt40 or mustang gt '88 fit?
