Paul,
In your water pump mods to lower it below the KIS cowl line, after cutting
off the stem, it looks in the photo that you also cut out the divider plate
to enlarge the channel.

What did you use to do this with, and how wide was the openin when you put in
the 3/16" plate?

I used a long half inch mill cutter but it can be done with
a die grinder. I ported it out as much as I could. I tried to
make the area of the channel equal to the area of the water
outlet port on the front end housing. Restricting the flow
to increase pressure in the block does not make sense. The 
rad alone will be restriction enough. If you need more pressure
in the block you can go to a 20 psi pressure cap and pressurize the
whole system without affecting the flow velocity.
