These are not specific to a 250 but are generally accepted I think.
Oil,Fuel,and Water Pumps: SECURELY to 20-25 ft.lbs
Valve Covers,Push Rod/Lifter Covers:7-8 ft.lbs.
Oil Pan:7-8 ft.lbs. except corner bolts 12-15 ft.lbs.
Don't overtighten and squish any cork gaskets and
make sure all bolt threads and threaded bores are clean.
Also, after running the engine for a while, check for leaks and loose bolts/nuts.

Here goes...for the 250 from my manual in ft-lbs:

some of these things dont matter too much though with torque specs...u probabl know which ones matter or not...but if u need more help than its no bother to give more.

thanks for the time and the torque specs.now ill start putting thing together.

Hey trueslayer, are you giving us Ford specs or Chevy specs? I thought you were a Ford guy.

The "sprocket to cam" and "pulley to damper bolt" gave you away.

UHHHH...HEHEHE...yea...FORD, sorry bout that, but most of the specs would still be the same being the same size engine...anyone care to clarify?
