Exhaust head bolts

[Eric Williams]

Does anybody know what the size in inches? I know what the threads are. I bought a set and they look like they're only about an inch and a half long. I'm guessing they're not right. Thanks, I appreciate it

Thanks Nick, I appreciate that. I know the thread size but is the total length 1.7 in? That's what I have but it seems too short when I screw it in it just keeps on going and then it's a lot shorter than the other side , unless one is supposed to be shorter than the other. I have one break off inside the head so I don't know what that side side is supposed to be but I believe they're all the same.

That is a standard size. I believe S&S has one that’s 1.91 inches also.

Make sure you screw the short threaded end into the head. It sshould bottom out and give you an inch of threads to work with. Just a suggestion.
