Most of that stuff will stay there,.all the plugs are one of, so no way in hell should you be able to plug something where it doesn't belong, I normally break all the bolts loose and leave then in place, there are two nuts those I do remove completely, after that I lift the top part of the intake with a the bolts still in place and just set it on a clean work table. The other bolts that actually hold something at the same time I label, take pictures, and pretty much for all this I follow the FSM specially when putting everything back together. Use dabs of gasket maker on each hole on the gasket to hold it against the valve covers and also on the sparkplug tube seals clean any excess gasket maker immediately after you are done tightening the bolts for a clean look, everything else follow the manual.It's all the crap that sits above the valve covers that scares me. I can do the basics and have the simple kit as well. Thanks for the input.
