Talk to Dwayne Porter at Porter Racing Heads. He can hook you up w/ whatever heads you need...802-951-1955
Personally I'd run either the Indy SR or the Indy EZ. The Edelbrock heads will do what you want, but you have much more room to grow in the future w/ either of the Indy heads. Not much more expensive either.

An SR or -1 head on a low deck block will use a standard 440 header. You run into issues w/ the SR and -1 heads (both have raised exhaust ports) on the RB blocks. You'd need either the TTI or Hedman headers for that specific combo.
