Thanks all for the replies.

The studs and mounting clamp things(what are they called?) is an interesting 
thing. Some were horribly rusted, and I did have to use a few bolts since a 
few of the original studs could not be salvaged. 

I did file down the pierce manifold to the best of my ability to ensure it 
wouldnt be pushed against the header. I didn't want to grind it down too much, 
creating a hole.

Here's an interesting thing though. The thickness of the flanges on the 
manifold and header are different. IIRC, the header's flanges are slightly 
thinner. This puts them at a slight angle. Can I just grind down a few of the 
old clamps at one side to compensate? 

I haven't been able to spray the carb cleaner on it, since once i start the 
engine, it dies as soon as I get out of the driver's seat.

Guess I'll just order all new studs, nuts and clamps then, just to start on a 
clean page.
