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 Shoot me a PM, on the zip/addy, & I trust that you will cover the shipping cost....or I don't really care about it....just pay it forward, to the next player longhorn

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 wonder if they are even grade 8 or class 10.9 metric....been researching this and seems to be a very popular topic so I guess it happens alot ! I think I was seeing red when I discovered this purple after the second one.

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.

Re: Header bolts size
Got my heads back and installed. We got most of the wiring done and computer hooked up sprayed some starter fluid inside the intake and it fired up for a couple of seconds hopefully in the next couple of weeks it will be able to start up and idling then just a bunch of little stuff after that
