Your not going to find anything to match it EXACTLY. It wouldnt make a HUGE difference if you just matched the ports (especially because your heads are bigger than your intake). You would only REALLY benefit if the whole intake was ported, because even if you open up the ports to match the heads, the inside of the intake is still going to be the same size. You can spend half a grand and get a bigger intake, or just stick with the gt40 which has been proven to flow good over 350hp. Or just get it fully ported by tmoss or something.

You can get some better input from tmoss though.

I don't think ill be pushing over 300 hp' right now my combo consists of an anderson ford motorsports cam N21 gt40x heads along with a cobra upper and lower , would it be safe to stay with this intake or would it be starving the motor for more air ' would i benifit any horse power if i get a bigger intake to match up my head runners.

Take the heads and intake to a good head/machine shop.
A place that does it right will mock up the heads and intake and use a scribe to mark out and port the heads to match the intake (or vice versa). They should valve job the heads while they are at it, as much as i like gt40x heads, their factory valve job leaves quite a bit to be desired.
You can make some noticeable extra hp with this work. Figure on blowing about $350 or so.
