Header bolts size
Ok one of the 100 little things I need to do is find some header bolts as I lost the manifold bolts when they were taken off and for some reason I cant seem to find them or at least decently priced ones. I have found some online but they dont say the size or thread pattern, I know they are metric Im thinking M8x1 or 1.25 does anyone know the size I need for my 07 5.3 ? and where to go to get some ? I went to the local Home Depot but all they had was SAE grade 8 not in metric tho...I refuse to pay the 30-60 bucks that these places i found want. they are just freaken bolts, somewhere there has to be a place I can go to find these at a reasonable price... thanks for any help oh and I am going with some shorty headers if that makes a difference

Re: Header bolts size
What I am finding it is an 8mm x 1.25 thread. Hit up lowes or home depot you should be able to get them for a couple bucks.

Re: Header bolts size
I have a set left over, from a set of Hooker shorties....I used studs/ nuts on mine? Yours for the mail price, but it may take a few days, from my spot in Illinois, to yours in Cali? They are black oxide bolts, nothing special....if you want them,I don't need anything , but the mail charge

Re: Header bolts size
Ya, thats what anti-seize was for...but most of us forget it. Thats also why the stud-style replacement has gotten more popular, as its much less likely to sheer at the nut.

Re: Header bolts size
I went with stainless bolts. not as common, as they're metric, but they are out there and should hold up pretty good.
