Small block combo suggestions

hello all. I'm looking for some suggestions on tweaking my combo.
67 cuda convert, 360 .030 over KB 107 pistons , X heads ,six pack intake XE 262h-10 cam 195 thermostat
Auto wt 2500 coverter ,3:55 rear gear
PS,PB wt front disc , CruiseControl
Carbs are stock jetting PV 6.5
Timing is 15 Int wt 35 total.
All n by 2300 rpm
I'm in to detonation wt just about any full throttle application. Have backed the timing down to 30 total.
So I'm fighting surging at 2200 in cruise and detonation on acceleration I'm installing a innvoate LC2 and hope to gather more data.
My ideas to solve problems are slow advance rate and look into transition circuit. Vacuum at idle in gear is 15"
Cam is installed straight up as instructed wt 110 LSA .
All opinions entainered
