right now i have hedmans on my 318 I have in there....ttight fit thats for sure had to lift the motor out to get them on...I wanted to get hooker headers cuz my dad has them on his 70 swinger and he said they fit really well...but I might get doug's or tti's go big or go home deal. I have power steering too but I'm going to manual steering for more room and my power steering leaks haha.
