But you are right the cost, castings are not cheep, will have to be cnc cut, seat registers cut and seats and guides installed. All this adds up. But if they can make the power right out of the gate i think it will be worth it to people. But at the same time i dont think its really any more than a lot of the alternative castings for those that are going after higher HP levels.

IMO where the 11 deg Pro-ports will shine is in efficiency. I really don't think they will make any more PEAK power than a Tiger head but they very well could make more AVERAGE power and torque with over a wider range with a slightly smaller port and shorter valve combo. As Calvin said, they will be pricey but for some applications they might the best choice. Time will tell....
