[Spridgets] Head Stud Torque Setting

[corvallis at peoplepc.com]

Some engines use the hollow push rods to lubricate the friction point at
either end of the push rod.  Bill in Oregon

I am removing the hollow tube pushrods from the 1275 in my Bug eye and
replacing them with standard solid pushrods.  I am doing this to prevent oil
from pooling on the top of the head.  This oil is being drawn into the
engine and hence the blue smoke on acceleration.   At least that is the
theory that David Anton agrees with.  The hollow pushrod diameter is not
much less than the hole in the head it passes through.  When I change the
oil it takes forever for the oil to drain down into the engine.  What I am
asking is about the torque setting for the head nuts.  My Haynes manual says
42 ft/pd or 50 ft/pd for studs marked "22" or have a drill point.  What are
they talking about?
