not too argue but machine in what way? there is no port work done at all. i have one of those hoca's just to see how they look.. and i am a machinist and i dont see anything that would be call'ed performance..just bigger valves then stock..but i would like to see a pic if anybody out there has any pics of the ports. sorry i aint buying it. there is nothing performance about it....
