So I'm looking around for some header bolts, the stock ones are kind of ridiculous in regards to clearance around my hooker Pro Comp headers, I lost two of the damn bolts in the floor drain.
Has anyone seen anything like this that will fit the small block?
I can't seem to find anything.
I don't have the car near me to grab a bolt and measure it, but I believe the ones pictured are larger for say, maybe the big block?
I'm not 100% certain on the size I need, I also don't trust these drop-down menus saying that it will fit your car
I use stage 8 locking fastener for headers. Summit has them and they also carry their own version that locks differently. Made out of stainless steel. On for two years now and never get loose. No leaks.
Those are cool, but what motor take 7/8" header bolts :rubeyes: That's a LARGE bolt :o

Wouldn't stainless bolts into cast iron cause an issue eventually?

That's the length of them

Odd way to advertise them :drunk: ...Are they 5/16 thread ? Would that not work for a Mopar ?

I had heard of issues but didn't know the specifics ... Folks here really run down SS hardware

Stainless fasteners are significantly weaker than carbon steel bolts in my experience. You are way more likely to spin the tool on the head or shear the bolt if it sticks. If clearance were an issue I would use a grade 8 cap screw, no reason to mess with the external hex head. That design in the picture is neither fish nor fowl.

Local hardware or farm store should have them, or order online.

Wow, $26 for 100! Maybe set up a "group buy", I'd get a set just to have around (:

I am running after market aluminum heads that comes with SS thread insert. To repair thread damage in steel or CI, SS thread insert is used all the time right? Steel and CI can rust together too, especially threads exposed to coolant in the factory heads. May be use anti-seize compound on the threads.
Liberal use of black moly paste on stinless fasteners during installation will prevent them from seizing in carbon steel.
