I have this intake, I run the holley 17 degree heads.. I have used the trick flow intake too, the holley is far and away the better intake for day to day driving. the trick flow has equal top end power but off the line , mid range to 6000 rpm the holeey wins hands down. Don't forget to go with bigger fuel rail / injectors too. Ray, 1995 5.0 GT/ tko manual.
