Basically yes, it's a good idea to clean out the bolt holes a bit to make sure you have a little space below the bottom of the bolt to avoid false torque readings. Long screwdriver, brake cleen, paper towel and/or shopvac whatever you want to rig up. Lightly oil and re-install, torque it down if it spun in all the way smoothly. As long as you don't use so much oil that it has nowhere to go when the bolt is bottomed and ready to tighten you're good to go. I've done this on 5 trucks now and haven't seen a bad head bolt yet. No head removal required for valve springs, I think you just need a valve spring compressor tool.
