    Great addition....

    These bolts work perfectly for any mustang header, in tight spots you may not be able to use the washers, so just use blue locktite and mr gasket lock washers.thanks AM

    Great buy if you are looking for header bolts!

    These arp bolts are awesome. They fit way better than standard bolts that come with most headers. The stainless finish gives a good look to them as well as protects them. I would deffinitely recommend this product.

    Great bolts, smaller size for the tight spaces

    I bought some Mac ceramic headers and the bolts that came with them were just too big and getting a wrench on them was impossible. I got these bolts which have a smaller head and it worked perfectly. American Muscle is a pleasure to do business with.

    Nice hardware!

    I used these to mount up a pair of shorty equal length Hooker headers and they worked beautifully. They're 3/4" long where the factory screws are 1", so the shorter length helps get the screw into the head when dealing with limited space. Make sure you have SAE wrenches since a socket probably won't fit when using larger aftermarket primaries.

    ARP Head Bolts

    After a plethora of auto stores didn't have the header bolts for my new shorty headers, I went to american muscle and they had exactly what I needed. The fit was great and since they are ARP I know they are good quality steel. They head of the bolt fit perfectly and made the install easy.

    Header bolts

    Well very simple, they're just bolts but definitely a great product. It's the little things that count and also the stainless steel puts a nice touch under the hood instead of the stock rusty black ones

    Good header bolts, but rust

    I needed new header bolts and bought these instead of using regular bolts. They sealed fine but would use torque wrench because if not they will come out. They did start to rust shortly after installing.

    A great name in the industry

    Decided to upgrade to the ARP from the bolts that came with my headers. Want to do the job once and know they will stay tight
