Paul,

  I am currently fitting the the sealing plates to the rotor housings
  including drilling and tapping into the water jacket.  In a previous
email
I
  saw a picture of the housing with a note that requires filing the web
  located at the top of the housing where the top edge of the sealing
plate
  meets the block.  Should this be done so that the plate can make better
  intimate contact with the housing so the amount of sealant can be
minimized?
  I also remember something about wrapping the plate and filling the void
  between the plate and rotor housing with something.  Then installing the
  plate with RTV,  Could you go over the procedure?  I also was wondering
if
  AN 3 bolts can be used in place of the 1/4-28 bolts as the plates have
less
  material than I am use to.  Thanks for any help.

  Right Joe. Use JB Weld to smooth the surface.

  Get some of this stuff from a yacht store and treat the aluminum  or the
JB
  Weld will not stick to the aluminum rotor housing.

  Use clear plastic film between the block and JB weld so the block
  does not stick.

  Then remove the plate. get rid of the plastic film and use a thin
  layer of RTV to seal the plate.

  Then pressure test it before you assemble the engine.

Paul,

Thanks,  I will alodine the surface.  Does RTV red go on the screw threads
also?

Yes.

If you find some pin hole leaks when you pressure test it you
can fix them with this stuff. The viscosity is almost as low as water
and it is liquid silicone good to 500 F.

I used the spray version of that product inside the waterjacket area.  Have
to build pressure test hardware.
