Does this sound like a good idea ?
 

I have the MSD 6AL box and I was told change my gap to .60 instead of my .54. will this be worth the trouble?

I don't know if you followed the topic on hyped spark plugs, but the answer would be yes. By not increasing the gap on your spark plugs you are essentially defeating the purpose of getting a high performance ignition. Since you have more voltage reaching the plug you can open up the gap to allow for a bigger, hotter spark at the same level of reliability that you would have with a stock ignition.
