Indy 360-2 230cnc oval Port

Hi Guys, as always i´m searching for more power.....kinda addictive i think. Thought about the readily available Heads, i do like the oval port / offset rocker heads like the W2 or the Indy 360-2 Version. It seems that these indy heads are not used very often - i can find more information about the 360-1 245cc rectangular version but i think these would be totally overkill for my application (pretty basic 408, 10:1). So let´s hear if there is some experience with these Indy 360-2 oval Port heads, with or without their available cnc-porting. Engine combinations, Horsepower / torque data, Quartermile times, cost involved - all is interesting. Thanks in advance!
