No, but your first time might take you over an hour.
Get your new Orange Bentley manual that Jason sent you. In there is the procedure.
There is one thing in there that the novice will find confusing. When they talk about using a feeler guage, they all talk about the correct amount of drag to feel when the gap is correct. What a load of crap! That's gotta be the stupidest most inaccurate way to use a feeler guage. The best way for anyone to use feeler guages is to use the go, no-go method. In your engine you will use the .006\" guage and the .007\" guage. Adjust the gap until the 6 goes while the 7 doesn't go. Then you know you have .006\".
Some guys like to measure the gap before they adjust to see how far off they are. Takes a while, but informative. Yesterday I heard about one guy that keeps a log book of his adjustments. I bet he waits until he gets home to take a crap too.
