Pi intake Q's

I have a line on a pi intake from a friend with some good camshafts. My question is i have a 95 4.6 i think this is for a 96 - up 4.6 would it still work i know i would have to get 96 up heads right? Now is there a pi intake that would fit my 95 and if so would i need to change heads to pi also or can i keep my stock heads for now as i have no funds for pi heads at the moment. If i can keep my stock heads with pi intake i can swap out the cam's for a better set with stock heads? Sorry for the long and dumb Q's but i really would like to know.
