iagree Out of those 3, I'd use the Indy -1 heads. The -1 heads on a low deck block will fit headers like a stock headed RB block. So the Indy headers you have, I assume are the TTI step headers for the raised port heads? Those likely will not work b/c they're made for the RB block w/ raised port heads. You can use any header for a stock port 440...like your Hookers.
