What most people don't realize is high compression is a good idea on a ve+t. The rules are different to det. The reason being you have 2 sets on cams. On a det too high compression and big boost can cause dangerous cylinder pressures especially in the mid to higher rpm. However people need to understand there is a difference between static compression and actual compression through the engine cycle.
On a det you can run higher static compression with bigger overlap cams, however this often makes the bottom end very doughy and unresponsive. But on a ve+t you get the responsive benefits down low high of compression and no overlap but as soon as the cams switch to the high overlap high lobes you are effectively lowering the actual compression the engine is running.
I think your set up will work very well. The n1 cams have plenty of overlap to run 11:1 comp. Just might need to switch to the high lobes a bit earlier than normal to keep things safe.
