Jon, no wonder you were always cold while driving, there's no heat exchanger on the driver's side!
The only difference that I can see is that you have the 901/01 blockoff plate, because your car is a Solex car.
While I've got your attention, can you describe your cam oil lines? Do they have ONE orange stripe or three? Mine have ONE and Cohline makes an oil hose with ONE, but I have seen THREE and I have seen a BLUE stripe, although to be true those were both on Center-lubed cars.
Did you use any particular technique for getting the case clean? The machine shop which will do the case squirters has requested that the case be spotless when they receive it.
