You will lose some really low end torque, like 1-2.5k RPM with mild cams like that, but beyond that it should start to pull ahead of stock cams. Losing torque in the 3-5k RPM range sounds like you got a cam a tooth off.

Easiest way to do a cam swap is zip tie the chain to the gears, take the gears off, then bolt them to the new cams (assuming your timing was good from the start).
