My S&S heads came with a half of a set (4). I guess they figured people were reusing the old HD ones.
They only come out of the head 1/2". The studs are 1/8" proud. The threads on the studs are 13/8"..
Since I'm buying new bolts I'm thinkin I might as well grab some more thread with longer ones.
Any reason not to?
How are the Diamond bolts?
ARP probably the best , but cost a little bit but the polished 12 point looks nice, not sure on length ,

The ones I have are too short. I have 3/4" more thread available so it isn't going to be a problem fitting the right ones.
There's that much room in the cylinder also.
When I looked at ARP they only showed 2 kits for older Harleys.
