The Andrews 438 cams require more than stock compression to function adequately, and even with a built motor, the S&S 495's are better. That being said, neither will work in your motor. They were designed before the newer closed loop 106 motors came out, and I don't believe will work with the cam carriers. Your only choice in a cam upgrade really is the VM1-DR cams from Lloydz. However, in my experience, they push the TQ curve higher and longer, so the rev xtend feature of the PC-V or Lloydz reprogrammed ECU would be a must. You will lose some low end torque with them too. Some of that can be reclaimed with Lloydz variable timing wheel (gear).
As for the labor, the motor does NOT need to come out. The shop that quoted you $2500 is clearly not aware of this fact. They also aren't aware that the 438's won't fit either.
As for the PC-V, for the price of the dyno tune you'll be paying for, just buy the piggyback auto tune module, and never have to pay for a dyno at all.
As an aside, I have the Lloydz VM1-DR cams, variable intake (Vision only), Ness twin sucker intake, Lloydz timing wheel advanced 2 degrees, and a PC-V with Autotune. My bike does not "pop".. EVER.... It took both the variable intake and the timing wheel for me to regain the low end torque I lost with the cams.
Honestly, if I were you, I'd try the new Cobra Power Pro CVT, and keep the setup you have, since low end torque is important to you. I would also make sure that you do indeed have the stage 1 flash loaded on your ECU.
