what size header bolts are needed for a 2000 f-150 w/5.4l.

i'm looking at some new headers, and need to know the size of the header bolts, so i can get some new one's?


thanks!!!

 

jgreen24; I installed the JBAs that I bought right here.The fit was right on,and they came with the bolts. If you go this route stop by your local hardware and buy some star locking washers.dont use the ones that come with the kit. with only 15lbs of torque the still ones dont lock good.where the stars do. hopes this helps...oldgray

 

thanks for the reply oldgray, but you don't recall what size they are ie, 3/8 etc...


thanks!!

 

My headers came with 8MM-1.25X30
The Stage 8 bolts for 4.6/5.4 are 1"
