why would you lose 20? parasitic loss does not go up, I smell some bs, no #'s had a bad plug wire so it will be some more time before we see the #'s what no one had a plug wire? special wire's?

Is the dark Blue run the previous heads? The date is 2015 so I'm guessing yes.
If so I was not expecting the 4k rpm & below torque loss.
Have you had a test spin?

Tx's for that, looking to forward to updates. 
When I swapped the heads the throttle response was frightening, still is I have to say. I went from POS cathedrals to nicely done cathedrals, not what you are doing.

For strip use, your gains are at 5.2K and above, but for road course work, you lost power before 4.5K instead (where it's needed the most since your not going to play rev ranger through the technical sections of the track and where most of your passing it going to take place).
Hence a good set of ported heads should be giving you increased HP across the board from idle up, and not just focusing on Max HP at max rev's; At the cost of HP at low to mid range instead.
