aluminium head questions

I know of 3 heads that will work (stock intake and exhaust ports and straight spark plugs):

Mopar Performance part #5153524
84cc open chamber
290 cfm intake flow
2.14/1.81 valves
Mancini mentions "452" casting... is this basically an aluminium version of the 452???

Mopar Performance part # 4876311
78cc closed chamber (Summit lists it as 84cc???)
290 cfm intake?
2.14/1.81 valves
Mancini compares the flow as being better then the "906"... is this basically an aluminium version of the 906?

440Source (Stealth)
80cc closed chamber
2.14/1.81 valves
280-290 cfm intake
They also offer a CNC ported version that sounds pretty nice:

315/230 cfm (intake/exhaust) @ .600" lift sounds pretty good for non-raised intake ports

My only concern w/ the Steath heads are the few negative feedbacks I've come across. I'm not sure if the folks that have negative comments about them have actually used them or if they're against them b/c they're not a name brand.

Of these 3, I would eliminate the open chamber MP. That leaves 2 choices. Am I missing any straight plug, closed chamber heads? I sure wish Indy made one.
