r u running race fuel or pump gas. i have a trinity stage4 head with 17cc domes and i run race gas. it made a huge difference

its gonna really depend on your dome size and other mods. if you slap it in there with 20-22 cc domes i doubt you are gonna feel much. if you run 19's with some porting and what not, then you will probably feel a gain.

Do they real run that much cooler?

With any size dome, you will increase compression and performance, most noticable on the bottom end. The horsepower increase varies with other mods. Cooling is also improved with most aftermarket heads.

i spoke with the previous owner and it has a stroker cam and wiseco pistons and the motor has been bore out. the bike is also a 2003. i run 93 octane in it. also we race this weekend and i outran all my friends except for 1. he outran me by 1/2 fourwheeler.

I'm guessing that you mean a stroker crank. If that is the case, there is going to be some more info needed to properly select and/or design the domes. It might be best to call the engine builder and get specifics on the porting, how the cylinders or head was spaced or modified and see if he has a recommendation.
