There should be a tag next to where your hood prop is that tells you the proper gap. I believe its .054 but I could be wrong

Any ignition upgrades? - A wider gap may perform better.

Boosted? - A narrower gap will be required.

You may be able to open the gap up a bit for better "flame kernel" exposure to the cylinder mixture.
It will require some experimenting and plug reading to find the optimum gap. Keep a log and record your findings for future tuning.

PITA I know, but it's all the little things that add up to a big difference in the end.
