Heater control valve modifications

["Andrew Proudfoot" <amproud@nf.sympatico.ca>]

Well listers, as a result of boredom (still waiting to get the 77 back from
my bodyguy) I decided to have a look at my spare heater valve. Figured I'd
do that much talked about modification, to increase flow, install it on the
car when it gets back and keep what's on it for my spare kit.
Question is where do the washers go on the stem? Inside the case, or outside
next to the C clip? or does it matter?

Thanks

myself)
