yes, but the engine is not disassembled.
if i get to installing the engine tonight or tomorrow I might grind down the shim to a lesser thickness if it's holding me up from installing the engine.
otherwise i'll get one from Subaru.
i've never heard of a burnt intake valve though or intake valves causing issues...so i'm also tempted to leave it.
wonder what Gloyale, GD, or Shawn would say to this one intake valve situation? well i guess they'd just say - adjust the valve!
1) Loosen cam caps slightly , slip a "J" shaped tool with an edge on it under the cam against the edge of the bucket.(Snap-on, Mac, Cornwell all sell this tool for shim replacement) to force the edge of the bucket down on the vavle......this will allow the shim to slip out. Measure it and buy a thinner shim.I think they are sold in .02mm increments....0.02~.04mm
2) remove cam entirely, remove bucket, grind tip of valve that protrudes above spring just a bit.....can't take too much or the stem tip will be below the spring retainer.....but you might get .005"(in) which should be enough to get in spec. this option really is best when the heads are off and the valve can be removed and ground...rather than on the engine.
3) leave it.......if you can get even any feeler in at all there is some space
