compression or flow?

@PRH

His quote from the other thread.
From the other post I have going about compression and flow, looks like the W-2 heads may be worthwhile. I have a Holley strip dominator for the W-2 heads.
What am I expecting? 500 HP would be nice. I just want a quick fast Dart! I have accumilated so many parts thru the years I need to quit collecting and build something and enjoy my dart. Its not much more that a painted shell at the moment. I could just as easily go with a 440, But not now.
Oh and I have a A833 4 speed and an blow proof belhousing.

PS its a sickness... Mopar sickness.

And I need to type slower and spell check. lol
