I have a friend who is going to be building a motor for his daughter's truck to race in a stock truck division. The question is which head would perform better for this task? Everything I have read leads me to think the 185 head will give more HP because of the 70cc chambers. But the smaller intake valve will hurt flow. Anybody having input would be helpful.

6 cc's isnt worth it exspecially with lower flow.

Ok I can see that but all the info on the web states that these heads (185) make 30 to 50 more HP. But that statement goes against the my gut feeling and you guy's as well.
