Cam for 400 chev /dart

Looking for cam ideas for combo
3.6 diff
26.1 tires
2500/3200 V/P convertor
compression 10.5 --11:1
team G S/P 7530
carb QFT 780 vac sec
Headers 1 3/4 , 4 into 1
rockers 1.65 scorpion endurance

Head Choices
195 afr comp 311cfm at .600 lift 1.92 pinch
Heads ,, Have access to 195 AFR Comp heads . All dyno sheets I see say heads are a limiting factor Peak Hp around 6100rpm and dies quickly even with a medium solid 250deg duration SR

Due to the dyno sheet of a 227 head [comp or street??] on a 400 with 260 deg duration SR cam .Peaks around 6800 rpm approx 2.34 pinch both comp and street . Same engine builder as above

*****AIM and my ideas
Hydraulic Roller cam---already have Morell link bar lifters
220 AFR COMP heads 2.180 pinch [not huge ] 322 cfm at .650lift
236--244 deg at .050 108-109 LSA
8-10 deg duration split to get engine to rev and full street exhaust
Peak hp at 6000 +/-
All finish by 6400 to 6500 rpm

Comparison to a Windsor 408 AFR 200 cc heads 2.160 pinch similar slightly higher head flow
