Throttle Body & Intake Manifold Polishing

[River6822@aol.com]

Although this issue has been covered in the archives, I still have a few 
questions.
I have an 88 80q I5.  There is a leak in the intake manifold gasket, or that 
it what I assume, so I have to take it apart anyway.

1) What should I use to polish the throttle body and the intake manifold ?

2) Is there a point where the throttle body and intake manifold can be too 
smooth ?
I can have the whole thing electropolished, but will it be too smooth ?
A friend voiced a concern that with carborated motors, you could get things 
too smooth and the fuel would not mix correctly.

3) Has anyone done this before, or even high grade polishing ?

TIA
