Then When you say cam gears set @ 5/5 you mean both advanced 5 deg??
If thats the case you will loose power advancing the EX cam I dont see any problem advancing the intake cam!!
I would port the ITB's and the adapter plate correctly and make sure the timing on the cams its set correctly!!
And give them a shot since they should perform better than a stock Intake manifold!!
I honestly think you have another mechanical problem (cam timing related) or vvl was not operating Church's Dyno its known to be a high reading Dyno so I think with the explanation you are giving that you tuned your motor on the low lobe!! Wich makes sense for the numbers you are posting!!!
Anyway back on topic I will open a new thread when I start working on these ITB's with pictures so people will understand the problem better on the ITB's
