Trick Flow small block heads

Here's the car ,
Right now
408, eddy heads, 11:5 compression , Lunati 60405(currently), dynamic 9"4300, 4:30 gear, 28"tire, 150-200 shot nitrous (haven't sprayed yet do to valvetraine issues) best time 11.64 N/A @3800 feet , poppin/rough above 5800rpm. 3/4 down track starts poppin all the way threw the lights.
I'd say that's not bad for running like **** and N/A with a hydraulic flat tappet And mild ported Eddy's.
I'd like to get it into the high 10s N/A. One day...

I think I'd get the issues with the current combo sorted out before I spent a bunch of money on parts.

My 340 with ported Edelbrocks and a hydraulic cam ran 11.60 @ 116 (1/4) on pump 93 at 3240# with 4.30 gears.

The same heads freshened with 2.05" intake valves on my 408 went 6.57 @ 104 (1/8) on pump 93 at 3260# with 4.10 gears.
