Just to confirm, you should take out the 0.20mm shim (if using 16%), so all that is left is the 0.10mm shim???
Yes, there are 2 shims, 0.1 and 0.2. Just take away the 0.2. Those are head shims not head clearance.
Be sure the head clearance should be 0.35~0.4 by soldiering test.
With 0.1 shim, the head clearance about 0.35
With 0.2 shim, the head clearance about 0.42
With 0.3 (Both 0.1 and 0.2) shims, he head clearance about 0.45. It's for 20% fuel.
With RP6 plug, it better for large track.
With P5, its better for small track with more pick up.
