I just pulled #7 and #8 plug since those were the easy ones. I am running rich. I have 78 on the passenger side and 83 on the drivers side. What number should I go with? I am using NGK-BCP6ES plugs gapped to .45. It is timed at 14 initial and 35 total. I am running aluminum manifold with blocked heat cross over.
