CRAP! I'm smoking!

And if you dont run a PCV; The throttle blade opening has to be increased to give the engine the idle-air that the cam demands. This upsets the transfer-port synchronization, and the idle/lowspeed mixture, and the PV calibration. The PVC is an excellent Idle-Air-Bypass tool, at least up to cams of less than 250* or so.This may be contributing to your plug color.And with incorrect idle/low speed ignition timing,also, may be at the root of the blue smoke.
I guess what Im getting at is this; before you tear into the engine, be sure the tune is right.
The Dyno only gets the WOT/full load, tuned. This is but a tiny part of a street motors life. Very tiny.
Its up to you to dial in the rest. Since I have no idea of your tuning skills,Im only suggesting that the tune isnt quite there yet.I am in no way suggesting that your tune is flat-out bad.
The biggest street cams I have ever tuned were maybe 250-260 degrees. I ran the PCV, without issue, and a single breather, and no drilled holes in the T-blades,and PLENTY of idle-timing.
Hope that helps.
