Which Stage VI heads???

So....there are the bare heads for $1480/pair, and I can install new Manley's for $200-300, and use my existing springs and retainers
Then there is the pair complete (crate engine heads) for $2000

Which????

is there a difference IN the heads???
if not,buy the $1400 and put your stuff in them!!

i don't know if there's adifferencs IN them or not...i'm guessing not...i think the big difference in price is the cost of the valves...the mopar valves are more expensive...
