Setup: Vitaras, t3t04e, 12 lbs, 93oct, dyno tuned by John Vega

According to zeal's compression calc, its 6.4:1

Now, normally I would run a 6 heat range, but I pulled 8's out of the motor just now and am worried they will be to hot. Should I play it safe and go 7s?

The 8's i pulled out are black and sooty.
