Both of those pics show me that this valve is different on both cars, or is it the way it's clocked? The valve I have, if installed, will actually be 180 out from Johns valve. If I install it with the flat gasket side facing the manifold outlet, which should be up, I think, then it definately will be opposite of Johns. Bullitts pic, from what little info is showing, leads me to believe that the valve I have is all wrong.
Here is a pic of what I have and you can see the difference. Doesn't even look close to me.
