I'd say 1* on either side of the 108 ICL is fine...
I hope so. I will try to get it running again this weekend but family birthdays may hinder thatit will run very different, especially down low.

First ride today. My seat of the pants assessment is that I have hit the jackpot. I do not have a racetrack to test it this year, but I have a backroad that works for some runs. Previously we could go up to 100 before having to shut it down. Today, I went to 106 in much shorter distance and looking at the datalog, I did not even give it full throttle and the time was about 10 seconds of acceleration. That is way faster than ever before. Now I want to drive it a bit so that the Sniper tunes itself and then get it on a Dyno. The previous runs only indicated about 350 HP. to run 12.3 seconds. next step is to assess the valve lash settings from a different thread.

Your crankshaft at Top Dead Center has not changed.
You advanced the cam 8 degrees and this advanced the ignition timing at the same time being the distributor is driven off of the camshaft.
Your new valve timing events are bringing in the fuel charge earlier.
Would think you would still want your initial ignition timing at around 15 degrees advance, not at the 23 degrees advance as it is set now. As an example ^^^^^.
The fuel charge is in the cylinder, when do you want to fire it? Too much advance and it is fighting itself as the piston is trying to get over the top, then back down the other side to do the work.
Take a timing light to see where it is set now, then back it down to your original desired settings.
