any one got a place that list the cc range of heads?.i could always do a fly cut to the stock pistons to get the clearance i need...12-1 was just an idea an a guess of where i would need to be at to get the 200hp goal.as 4 the fuel system i figured i would have to go to bigger injectors.

whats the bore and stroke on them and how long are the rods..also whats the valve size on most of them heads..


the side load on the rings i wouldn't think would be that much greater of a load with just a 1k more rpms..maybe its just the ring package on the stock pistons..
