That little bump in compression won't make much difference at idle. The cam overlap is whats doing everything.

Considering that a well tuned Hot Cam LT4 should idle in the 40-45Kpa range @800RPM I personally think he needs to drop about 3-4* of advance in that range to smooth the idle out... BUT there is still the problem of over fueling at idle which when fixed may totally negate the need to screw with the timing table.

Honestly, I'm not the guy to talk to about the specifics of tuning. Engine building and machining, I'm more than competent on.... With tuning I'm just knowledgeable enough to get my self in trouble and I've always got Ed to bail me out (for a fee)....
