First, buy or borrow the factory shop manual and a Haynes manual for your car. Also, you must read them... I know of people who have them but don't read them... You are totally taking away the items which constitute a valve adjustment.. so yes,,, as you put it back together you will be doing a valve adjustment. The offset installer tool, bent valve adjustment wrenches, spring retainer wrench,new valve cover gasket,feeler gauges,the seals and the protective sleeves....would be my off hand recommendations for stuff to have on hand before starting...I know what you mean about the jeans... I switched to Walmart Rustler @ $10 to $12 myself...
