Stock compression? Go for it. Compression is a bigger issue than your ignition system when it comes to deciding your best gap, but ignition quality is important. If your running stock compression, and spent the money on ignition "upgrades", then go ahead and take it up to .060", if you want to, but listen for pinging.
