where can I find arp header bolts??
 

Like the title says I'm looking to purchase ss 1" header arp header bolts. I believe they are $34 or something. Sponsors shoot me a pm.

I wasn't aware they made actual header bolts - I thought they only had the studs (which are way more expensive).

so are you trying to find the cheapest place or just a place that sells them?

here is one:

summitracing


here's a part number to get you started on your summit search
ARP-400-1210

I guess not...

They are not ARP-400-1210 as you can see in the picture when they arrived this morning. Does anyone sell them or do I have to find a local store?

Call ARP and ask for a part number that is correct? I only know the part number for the studs, which is what I have.

if you do a search, you'll see that several different people have used that bolt.

it's 1" long.

If you were to search summit but under the year, make, model and engine size () they actually have the .75" long bolt.

the threads match in length, the tip of the bolt has no threads, I don't think it'll add much of a benefit.


here's where I originally came up w/ the arp bolts decision, several months ago.

there are other threads, that actually used the part number for the arp.

those WILL NOT FIT an ls1.
looking at the threads will tell you....

but read the package. it says 3/8 right on it.
thats small block/big block stuff.

arp only makes studs for the ls1.

the last time i checked they only make studs i am also looking for header bolts. may just go and get stainless bolts from west marine the boating store

i got stainless locking bolts from stage 8 on my car

Why don't you just go to a bolt store... that's what I did. Go to Fastenal or your local construction bolt place. 8mm x 25, stainless, allen socket head... $.50 each
