head torqing question
« on: April 09, 2014, 07:56:02 PM »
when using HD studs, what torque values do you use for the 4 screws under the pucks & the 2 for/aft of the cam tunnel?

I would guess it has to be stock specs so the threads don't pull out but then when I over analyze it (as usual) it seems that if the 6 non-HD fasteners aren't torqued the same as the studs then the head will be subject to uneven clamp force & could warp. ??
