Heads, which ones when....

Fair enough, I have this small block as you know, I want to run in the low 11s to high 10s, the car already ran in the 11s but I like to run in on the street really, enjoy it more like that but I want it to be able to run consistent mid 11s... Without the bottle.
Gotcha. Some ported Edelbrocks would work well for this, or the new Trick flows. Both of these heads would give you the potential to get into the low 11's to high 10 second range with your current setup.

Sorry, I didn't see it, but what heads are currently on the car? Ported cast iron?
