What heads do you plan on running? The Dart line-up would work very well be it Pro 1 or Iron Eagle. They offer many different sizes and configurations. You can choose the style that best fits your needs off their recommendation charts. Here are a few:

165cc----street/strip performance & towing w/stock engine.
180cc----street performance, max torque/response under 350ci.
200cc----street/strip performance, 327-350, 6000rpm
215cc----serious street/strip perf. 383-400, 7000rpm

Hope this helps. Might can get more info at WWW.DARTHEADS.COM
