Mudbuster cam in a 550 grizzly???

I have a 2009 550 grizzly. Running JBS extreme kit, 1mm shim, 1000rpm stall springs instead of the slugs, gold secondary spring, snorkel, HMF penland pro with the optimizer, k&n air filter… My question is both the 2009 550 & 700 share the same cam. Hot cams offers a mudbuster can for the 700 but not the 550. I called Hot cams and asked if they would interchange and after reviewing it they called me back and said yes. Can anyone tell me a reason not to try this?
