Roller rocker questions

Hi all,
  I have a set of roller rockers for a Chevy small block I'm thinking about
putting on the Dak, and was wondering where's the best place to pick up the
stud conversion kit. I talked to one guy and was told that you don't need
the kit, but he sounded like he was talking out a lower orifice. I've
rebuilt several 340's, but this will be my first dig into a Magnum, so I'm
not really sure. Also, for those who have done the swap, what Valve covers
are you using? Cranes site says they won't fit under the stock'ies.

TIA,
Mark

Also, the discussion about cranking off the torsion bars to lower a 4WD,
someone said doing this will put the front axle shafts in bind. I talked to
a friend who runs an alignment shop about this and my doubts about it, and
he backed me up on my thoughts. You can crank off on the front torsion bars
as much as you want, all you will do is reduce the amount of wheel travel
available. The "rate" of the torsion bar stays true, because the bar is
still "lifting" the same weight, (front of your truck) regardless of how
high you lift it. But by not lifting it to factory spec's, the front
suspension will bottom out before they hit maximum rate, which makes it seem
like it bottoms out easier( because it is, the extra travel that would
normally absorb the hard hits isn't available) As for the bind issue, it's
not true. That would be like saying that Dodge designed the front suspension
to bind every time the suspension was loaded. Think about it, when your off
road, are your front axles binding every time you go through a dip or
bounce? The A-arms and axles are designed to go through their full range of
motion with out binding, so reducing the range of motion will not induce
binding. I'm writing a letter to Performance Suspension Technology in NJ.
about their high rate/heavy duty torsion bars for putting big blocks into or
racing A-Bodies, to see if they could make a higher rate bar for daks that
could be used for something like lowering a little or off-road performance.
I'll post if I hear anything promising.
