The ET's are awesome if you want to spend a few hundred more including the rocker stands. They are an 11* vs AFR's 15* head so you will get slightly better flow characteristics and more PVC. Plus the bigger runner might be better if you plan on a good size cam.
I went the AFR route, mild cam and milled heads. You will be happy either way. The ET's are awesome though.

ETP are super sweet and make a ton of power.
ETP Cons
Valve Cover Spacers
New Pushrods
On my corvette you have to swing the alternator out
Fuel Rail covers don't fit(corvette)
AFR's are true bolt-on's. You can use the stock pushrods, valve covers, fuel rail covers. And you know how much power your going to make.
AFR cons make a lil less horsepower then ETP's, should mill, maybe lose 20rwhp at most.

New pushrods most likely will be required with any head, especially a head that has some milling.

what do you mean when you say, "should mill, maybe lose 20rwhp at most"?

If you want to run a bigger cam and not fly-cut, go with the etp's. If you need a carb # and don't want to wait too long, go with the afr's. Both good choices.
