It's a pain in the ass to get in the cams if you still got all that stock airbox stuff in there, plus removing plugs, wires and coils is other bit of tedium. Just requires time though. You will need the relevant parts of the service manual to remove and install cam shafts correctly. Cam timing and valves are not something you want to mess up. I'm pretty squeemish doing that myself but I have little experience dismantling engines. You'll probably ok, Frocket, with your experience.
