Sorry, I meant to take the plug wire s off the cap, spin the cap 180 degrees and reinstall it. Then reattached the plug wires again.

Another question. What type of header bolts are you running and have you check them for tightness? I'm suspecting you may have a blown header gasket. Easy to check at idle with a BBQ gas lighter.
When I bought my BDR, I found 3 header bolts missing on the right bank and 2 missing on the left @ 785 miles on the odometer. I installed ARP Drilled head header bolts and Inconel safety wire.
