408 aluminum head choice for 500Hp

Ok my Plans are to:
Use aluminum heads
Use as high compression by utilizing good quench on 92 octane
forged Crank, Rods, Pistons(Custom pistons an option)
Magnum 360 Block for Roller cam (Prefer Hyd Roller but Solid roller if necessary)
6000 RPM (I like high winding motors)
Carb And Good ole fashion dist. (Simply because I like working on em for tuning, Much more fun than a laptop)
Head studs and MLS head gaskets.
2800 to 3500 stall converter on a 727.
Gears will be decided once the engine is figured out.
Car will be registered and street driven. However it will not be a cruiser, I want a hot street car. Dont care if it loads up the carb every now and then. However I will be driving it on the street around town, highway driving not in the plans. MPG not much of an issue either. Oh yea the only accessory that the car will need is Power breaks. No power stearing. No AC. I only want to drive a water pump and alternator.

OK my question is, what are the best choice of aluminum heads for a combo like this? I keep reading that the Eddys arent that great. I have read alot about RHS iron heads but I want the temperature control and Weight loss of the Aluminum heads. Also I am trying to keep my head purchase under $2000

Whats everybody think? I havent decided on a cam but I do understand that a Cam and Head purchase at the same time is much better than trying to figure out how to make mismatched parts work.

Thanks.






Ok here is my question I want to make something between 475-525 horsepower
