Exhaust valves are marked EH . inlet valves are marked IH . The shims are fitted underneath the buckets. Cams on the left side head are marked L4EX and L4IN . They have 2 grooves around the lettering, one is after the 4 and one is to the right of the last letter. If you take a valve spring out and measure it, It should be 56mm .
If you're not sure, post some pictures.
