I called Sears , Autozone blah blah blah said they had the metric in stock. What they meant was they had the standard with metric three digit number stamped on it. Not the same as the metric gauge, the numbers stamped on the standard set need rounded up or down leaving a small varience. I did fall within the tolerances so I am not to concerned right now. When I need to do the adjustment I would like to be a bit more exact. Here is how the standard size and metric size compare.
Standard-Metric
.006 - .15
.007 - .18
.008 - .20
.009 - .23
.010 - .25
.011 - .28
.012 - .31
As you can see the metric is missing increaments using a standard gauge. Not a problem as long as you are within the spec's. Once I fall outside the spec it would be nice to start as close to exact as possible. Not critiacal but nice to know. This is my first experience with an overhead cam. When I took the cam cover off I was not sure what I had. It is starting to come together. Not like the good old push rod tappet days.
