Low 12 high 11 sec intakes

[HORSEMEN RACING]

Back again,
I am asking this and hope I get the same feedback I got with the "NA Street Combos".
First let me explain to you what I have,and tell me what needs to be replaced:
I have a Cobra intake with 60mm throttle body,ported stock MAF sensor,Mac 1 5/8 shorty headers,into a Mac h-pipe with converters,E303 cam,1.6 bolt down roller rockers,underdrive pulleys,PS-91 coil,9mm Motorsport wires,adj regulator.
The parts I have in are TFW Twisted Wedge heads with a Fox Lake Stage 1 port 280/210,Custom cam .555/.557,cold air induction,75mm calibrated maf sensor,24 pound injectors.
Do you all think the Cobra intake is stout enough,or should I replace it with a Holley Systemaxx or TFS intake? Like the subject line says looking for low 12's high 11's.
I hate to keep bugging you all but I am real curious about this one because once again in NMRA the "Factory Stock" cars are running low 12's high 11's with out of the box intakes and most of those are Cobra/GT40 intakes.
Thanks guys and gals for any feedback you can offer.
