isnt it something like snug + 1/16 of a turn? It says on the back of the package.

Snug for sure, and I agree with matt, after the SD header install I can tell that rolling the engine forward won't be needed anymore.

Just changed my plugs to copper Autolites @ 45K. To me the stock iridiums feel better at tip-in (light throttle). I'm pretty much stock except for custom intake but I think I'll go back to stock iridiums. It's a daily driving that I do tend to push hard quite a bit but don't have time to change plugs every 10K+.
