I need 8 exhaust studs from a Coyote engine. Hopefully someone changed to bolts and have some on hand. I shortened some of mine to use the stud and nuts, but forgot to allow for gasket thickness. They will work, but would like a few more threads showing through the steel lock nut.
Let me know how much and shipping cost and I will follow up.
Thanks,

I have 8 studs that you can have, just pay for shipping. Do you want the nuts too? PM me with your address.

I want to acknowledge the help from Ducky2009 for providing the exhaust studs for my engine.
A greatly appreciated gesture of help and generosity from a fellow FFR owner.

Is there a reason you stuck with studs instead of using the new bolts? I was starting at my engine contemplating the same thing last night... any help appreciated!

I have used both on various engines and have had better luck with studs/nuts staying tight and getting gaskets and headers aligned on installation. I can easily access all on the passenger side and some on the drivers side. Some I had to shorten and messed up, as mentioned above. I bought a set of Stage Eight bolts with the E clips and wings, if I have any problems. On another note, all the threads on the aftermarket bolts look like they are dropped at some point before final packaging. I will run a thread restorer over them, to avoid damage to the threads in the heads. I have not compared length, but the studs look like they go deeper into the heads than the aftermarket bolts. I think the threads on the nut side of the studs are a finer thread, than those on the head side, thus better clamping and more resistance to loosening.
I hope there is an answer to your inquiry, somewhere in my ramblings.

Not a Coyote but I've had great luck with allen socket set screws as studs. Pick the length, buy the nuts that work for the application. With studs you can bottom the screws getting as much thread engagement into the head as possible, then the studs act as hangers when mounting the gaskets and headers. This may not be the cool ARP solution but only costs about $15-20 including the screws, washers & nuts and you'll have extras. www.McMaster.com
