Look AFR is the master of cylinder heads. They originally started out by making cylinder heads for stock car racing for chevys. Then about 2-3 years ago they developed a SBF head. Right now they are the best quality and best all around head as well as the best performing head and they are within a couple hundred dollars of their competition.

Did you see how broad that torque band was. You will have decent low end and then amazing mid and top end power. Those dyno numbers are accurate. One thing about AFR is that they dont fudge their numbers. They are very fair and honest about that stuff. You can tell because the Mustang Mags have proven that with independent tests their heads are amazing at flowing more with less. Meaning they have more average and peak flow of air using smaller runners and valves. They also increase power across the whole rpm band by having the highest compression. Remember this is all out of the box. If you go with the cheaper head companies you will easily spend the difference for port work and valve jobs to make them flow like AFR's and risk using a bad shop etc. Just by the parts right and be done with it.

To by the right parts you need to make a list of what you want out of this motor. Right down what you will be using it for mostly, how much power you want, and how much money you are willing to spend. Then you should call Ed Curtis who is also a AFR and TW dealer as well as the best cam maker in SBF world and have him put something together for you. I believe that AFR also has an intake manifold for your carb setup but that may be strictly for race and not streetable.

According to AFR they are currently developing heads for the 428 CJ but those wont be coming out for another year or two. That is a heads up for all of us new cobra car guys going with the BBF setup.

The quality of AFR is unmatched even by Ford and their R&D is impeccable. Now be prepared to wait a month to get your heads as they are ALWAYS back ordered.

Look if you want to go with doing it right the first time it may cost you some money in labor to have the pistons notched, gaskets, misc parts, etc so you need to really find out what your top dollar budget. If you go with the 185cc heads which I would advise if you are going to keep the motor and later do a stroker rebuild later then you will probably have to notch your pistons. Or you cuold just get new probe or JE pistons that are dished. but then you have to tear down the bottom end which can be a pain. You have a lot of options so it is now up to you to do your homework. You can buy a bunch of the nicest parts on the market and end they may not work good together. It is all about the combo.
