I decided to do a valve adjustment since I am approaching the Inspection II point and I took my valve cover and intake plenum off for painting. I created the attached chart for recording the values and doing the math to calculate what shims I need. Thought I'd share it with the forum in case anyone else wants to use it..
It has the values from my car in it; just replace the Clearance and Measured Shim columns with your numbers.
I did mine in inches since all of my tools measure in inches so if you do it in metric you need to change the value in the required shim calculation (change the desired # at the bottom)
Lastly, you need to look at the Required Shim (mm) and decide if you want ot round up or down to the nearest .05 - I didn't feel like writing the necessary embedded code to make Excel do the work.
*I usually choose rounding down so that you get a slightly larger initial clearance as that should shrink with time as the engine runs due to wear on the inside of the head where the valve sits.
