If that supposition is correct, then potentially either a Windsor or Cleveland thermostat could be blocked from fully opening if the disc in the block was solid.  There is a significant amount of vertical travel when the thermostat fully opens and although I never thought about it until now, and don’t have an engine to reference to test the hypothesis, it wouldn’t surprise me if you have hit on yet another disadvantage to modifying the cooling system in this manner.

   Jack,
   I buy thermostats for people all the time. Conventional OEM-style
   thermostats for the 351C cost the same as their Windsor counterparts,
   around $7.  It's true that since Robertshaw discontinued their 351C
   model, if you want a Robertshaw thermostat you have to buy one that has
   been customized from a Windsor model, from Marlin Jack, and due to the
   amount of work involved, those are very expensive indeed!
   The pressed-on `hat' on the Cleveland thermostat adds to its diameter
   to partially (not fully) obstruct the orifice in the disc in the block,
   but I don't believe it adds significantly to its height?  If that
   supposition is correct, then potentially either a Windsor or Cleveland
   thermostat could be blocked from fully opening if the disc in the block
   was solid.  There is a significant amount of vertical travel when the
   thermostat fully opens and although I never thought about it until now,
   and don't have an engine to reference to test the hypothesis, it
   wouldn't surprise me if you have hit on yet another disadvantage to
   modifying the cooling system in this manner.

        See the link below and the description of 2 flavors of restrictor

        plate.  My engine has the solid aluminum plate with the tiny
     hole.

      But

        I have always run the 351C unique thermostat.  My engine has
     always

      run

        a bit hot, usually over 200, even on the highway.  I noticed this

        article says "This unit (restrictor plate with the tiny hole)
     must be

        used in conjunction with a [1]standard thermostat , you cannot
     use

      the

        351C unique thermostat with this block off plate."

        Does anyone know if this is true?  Could this be the reason my
     engine

        runs hot?  Actually my engine currently doesn't run at all due to
     a

        destroyed rod journal.  My engine is currently out and in pieces,
     so

        I'm wondering if I should change to the original big-hole
     restrictor

      or

        keep the small-hole restrictor and switch to a non-351c standard

        thermostat.
