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
What people forget is a good bowl blend and any port work done also installing larger valves change the flow characteristic's of cylinder heads.I would tend to choose a smaller head for any street car to try and keep the port velocity a little better.After all you won't be lauching the car at 5,000 r.p.m.s at every light.
