well if your gonna stay NA the Cobra intake is perfect, I'd consider either AFR165's or TFS heads instead of GT40, as for the cam, F303 maybe? get some 1.6 roller rockers for sure and make, i wouldnt go any higher than 9.5:1
if you are gonna rebuild it then you will need to bore it .030 over, this will take your displacement to 306ci, still a 5.0 though, depending on how radical of a cam you go with, you may have to convert to mass air, its not hard to do, i did it recently just to get rid of a small surge in my idle, i only spent a total of $150 to do mine with a 75mm Pro-m meter that i got used for cheap
good luck with it
