I just removed the resistors, which was incredibly difficult, my 15w iron didn't seem to melt the factory solder very well, and then just cut small wires, tinned them and soldered that between the points. The difference between 400 and 433 is like, nothing.

When overclocking Macs - by resistor removal - I too try to rebuild the bridges using the existing resistors, as not all of them are zero K shorts. If I lose the resistors, I find conductive ink to be better to work with, to avoid damaging the fragile solder pads with too much heat.

With a ~ 25 - 30W fine-tipped soldering iron, to remove the resistor I place the point in the corner of the resistor and "flick" it upwards. The resistors should be sitting up where it can be removed with some tweezers with little effort.

I'm currently overclocking my Indigo iMac 500 @ 600Mhz - I reckon it could go more as it's the 750CXE processor-based board. My flower power iMac 500 (with ceramic G3) only got to 550Mhz.
