I have a 2000 f150 with 5.4l, I put headers on and got the driver side done perfect but had tough time especially with getting studs out but got all but 1 on back passenger and used regular studs and also torque bolts, since it's a shorty header I had tough time putting bolts on if anyone knows someone who could remove the stud (attempt) and fix the leak or who knows what they're doing since i cant find anyone out here that would/can and would work on it for me I would greatly appreciate it I'm located in clarksville/stationed at ft campbell
