    Does anyone have the thread size and count of the head studs on a 355 (the outside ones that get a nut, not the ones in the block)? The nut itself gets a 15mm wrench if my memory serves me. And if so, would they happen to be able to look up the part number?

    For example, the 308qv has an 11mm x 1mm and gets a 15mm wrench.

    Thanks.

    The nut is a M11x1, pretorque to 60 then using special tool 9570034 with attachment 2595 turn an additional 90 degrees.

    Thanks Mitch. I'm pretty familiar with the torqueing process. Would you happen to have the part number of the nut itself?

    Unfortunately I don't have a 355 WSM so I can't look it up.

    No, other than it looks like a 12-point, sorry.
