Looking for a complete roller

Here it is getting broke in after sitting for 3 years never fired.
570 Horsepower @5,700 rpm and 549 ft lbs of torque at4,100 rpm, with a 850 carb, and headers that were to big. Going to get a new 950 ordered today and take my TTI headers. The builder said he thinks the next pulls with new carb and headers will be 600 horsepower and 565 ft lbs of torque. That is on pump 91 gas station ethanol gas.
