Well...
Whether or not the butterflys are SUPPOSED TO touch the sides of the
throttle body is entirely beside the point, because they DO!

I believe that Marks original question (and now mine too) is :

1.) Can we resurface or fill in the grooves in the throttle bodies to once
again make a positive seal with the butterflies?
2.) By what method would list members suggest that this be done?

Take care,
