408 aluminum head choice for 500Hp

My eddy heads had been gone through by a previous owner. I didn't get flow data on them but the stroker runs great for what you are describing. Don't know if $2K will get the heads done but they seem to work OK. 10-1, pump gas. BTW, 6K is nothing, let it spin!

I don't have power breaks or steering and do not miss it. Elec water pump is working fine but I do not sit in traffic. Only accessory is the alternator.
