Assuming that you have it backward (.13mm on the intakes and .22 on the exhausts), they're fine.

If you meant it the way you posted it, they need to be corrected.

The size shim you need cannot be determined without knowing two things: the difference between the correct and the measured clearance, and the size of the current shim on the valve in question. There is no single standard shim size.

to determine the shim size pullout the cams and lifters and read the number on the shim. if you cant read the number use a micrometer to figure out the size. you can then use the chart to figure out the new size you need.
