Yes, still use the washers with HD studs.
That's what I thought, but just wanted to make sure.
However, now I have another question and it's irksome. So I tightened all my cylinder studs the same torque spec, in the appropriate sequence and I've found that after I followed the correct sequence for tightening down my head nuts, most of the tips of the studs come thru to what I imagine is the correct spot, whilst some of the tips only go about 3/4 of the way thru. Is this a problem or is it acceptable? They were all tightened to 22 ft lbs as per the instructions from Kibblewhite.
