[Vwdiesel] 1.6 mm head stud kit

[Andrew .Libby]

There weren't any VW TD engines with 11mm studs.

The difference with the newly released TDI/IDI stud kit is added tensile
strength to accommodate additional torque for proper sealing of the head
gasket when using the later multi-layer-steel gaskets which require more
clamping force to seal well.  If using the older 1.6 fiber gasket, the
Cosworth studs work very well.  I have also quite successfully used the
Cosworth studs with the later MLS gaskets and torqued to 90+ ft. lbs.
