Heads, which ones when....

Just so I'm understanding you correctly, your current motor makes 350-400hp and you want to upgrade, correct? Also street only, correct?

What exactly are you looking for (HP #, or ET#)....it is easier to make a suggestion if there is a specific goal in mind. All engine parts (the combo) need to work together to make the most of them, which is why I'm asking.

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.
