How deep are your pockets? That is the question.
You can use pretty much any cathedral head you want on that motor. AFR 230's would be a good choice on this.
As far as rectangular port there is a slew of them. You can run and LS3 head or the aftermarket LS3's from MAST or PRC. You can also run a small bore LS7 setup like the PRC small bore LS7 heads or the RHS LS7 heads.
If I didn't have the heads or intake yet I would go LS7.
As far as cam, I would contact Geoff@EPS or PatG on here to custom spec you something. It's barely much more than an off the shelf cam.

The good thing about AFR's is that you can run the stock valvetrain unlike Trickflows because of the different valve guides.

I would definitely recommend taking a look at our PRC LS7 small bore heads. They will fit on top of that motor and I would expect them to make some pretty good power. One of our customers recently put these heads on top of a 429 LS3 race motor. While it did have higher compression he was able to get 604 at the tire through a 4l80E transmission. While this is not the same as your setup it gives you an idea what these are capable of.

So in the end add a minumum of 500 bucks to the price of the heads.
Any other head can run the stock rockers of aftermarkets if you choose.

Trick Flow indeed recommends aftermarket roller rockers, but lots of folks are running stock rockers, usually with trunion upgrades. You need to shim the rockers though to get the geometry right. TEA has a kit with everything you need including the right length pushrods. Thunder Racing sells these kits.

Call Phil @ AI, tell him your build, what its designed purpose is (dedicated track car, street/strip etc), how many miles a year you plan on driving it.....and he will hook you up with a knockout setup. I've run AI heads on 3 different motors, and all of them have run as well or better than other similar cube motors, running ANY other head combo. Don't get into chasing dyno #'s or flow #'s...
