For starters.....Being a Cortina what pipes (extractors) are you using?? custom or castle auto's etc?? If not customs i'd say a good set of 13/4 or 1 7/8 4-1's and twin 21/2 or 3" X pipe etc. And maybe a better ECU if you haven't already.. I'm a little sus on them pro comp products now as my old TD has broken 2 of their roller rockers atm and its only got a Crane 236/240 @.050 and .536thou lift hyd cam. Hmmm what else....
Throttle body upgrade, manifold spacer, being EFI maybe a different tuner, get the heads ported plus nick a little off the face for more compression and with a bigger cam it'll still be fine for PULP.. Read some Muscle Mustang mags there are a lot of tricks in there. Myself I'd also find a "real" good cam guy and let them have a look doing a custom cam. I know Mick at HOGG Performance in Brisbane and he's finding so much more just by a lot of little changes with in the cam and lots of engine dyno time (he wont tell all his tricks) Maybe even give him a call even just for a chat, he could work something out for you (07) 33764333. What hp he is making while still using his cast 2v and 4v heads is crazy......
All the best
