Exhaust manifold stud length and thread pitch?

[Jon]

Does anyone know how long the exhaust manifold studs are AND what their thread pitch are on an F22?
It's still dark outside and cold so I don't want to run outside and remove one.

I believe diameter & thread pitch are 8 x 1.25 mm

I don't know the length. I use two 8 x 1.25 flange nuts (spare Honda parts) and double nut them to remove the studs, you'll have enough thread on the stud to make it work.

38mm length studs, just looked it up.

Thanks, just didn't want to go out there and remove a stud to find out.

EDIT: Yeah removing them is easy. I'm looking at getting some new stainless studs made for when I get the Bisi header. Yes I know I can buy stainless studs, but why buy them when I can make them for less!
