Here are some flow numbers on the Dart SHP. Honestly not very impressive. They were flowed on a 4.155" bore which will show higher numbers than a realistic 4-4.060" bore.

I do actually like those patriot heads...maybe I'll exchange the darts since I ordered them last night 🙁
190cc intake runner seems a little on the big side for what I'm doing...but if I go with the 1.6 rockers and change springs on patriots I think they would be right at home

A 200, 190, 180 cc runner isn't going to kill a street car. i agree the larger the runner the less low rpm power the car will have. It is all about air velocity going into the runner. Smaller runners allow for more torque at lower RPM's. Once you go wide open throttle though the 200's will out perform the 180's. Once your wide open, but your gonna spend more time at part throttle driving around on the street so it's really a judgement call on how your going to be driving. I would choose my heads off of the flow numbers around the engine rpm and lifts I would be running and the type of driving. Really any of the heads you have listed or have been recommended will work just fine. I just believe for aluminum AFR makes the best but your gonna pay for it. What is your horsepower goal?
