Yeah sounds like Dart's the way to go, but they are a good deal more expensive than the World heads (800 against 600 bucks including freight). And I've heard that Dart and World are affiliated somehow, but that doesn't mean the heads are the same or even similar. The chamber shape and swirl is better on the Dart (from what I've heard), but I wanted to know how much difference there is and how much difference will I feel in terms of torque and mileage as opposed to 186s or 041s or 192s or 601s (which are basically all the same), which I can have for 300 bucks a pair reconed...
Thanks for all the input,
Max

What do you think about these heads? They seem to have goodish chambers and they're 58cc, so with a .100 D-dish I should get 10:1 CR, which is what I'm aiming for. looks like I'll get a good quench area and the valves are nicely deshrouded... PLEASE DON'T BID ON THESE HEADS, THEY'RE MINE
