That jet spread will mess you up BAD unless you have a huge PVCR in the primary metering block! The rear 2 plugs are likely going to look much different than the front 2.

If you have the stock primary metering block go up 3 in the primary and down 3 in the secondaries. Something in the range of 75-83 or 76-82.
