So I just threw some Not Even Slinky 56 gauges onto my crappy old strat and the bridge is being pulled up. How do I correct this? Is it just not a good idea to use heavy gauges on whammy bridges?

You can tighten the two screws that hold the tremolo claw (take the back panel off to access them), but you might need more springs as well with such heavy strings.

I have three springs in there already. Tightening the tremolo claw doesn't seem to do much. Is there anything else I can do?

can you put two more springs in there? most strats will have space for up to 5 springs.

You need more springs dude, that's the answer

Slacken the strings and put 5 springs in it, tighten the claw a fair way in.
Tune the strings to pitch
Loosen the screws until the bridge starts to lift ever so slightly
Retune the strings if required

This should give you just enough tension for the strings without meaning the trems to hard to push.
