Engine TFS Valve spring kit shims

[sav22rem22]

So I got the TFS valve spring upgrade kit #TFS-2500100. I’ve just went through and shimmed all the valve seats using the supplied gauge and shims. Most of them went pretty well however I have two or three valves across both heads that I just can’t find a comfortable medium of clearance. Would you all shoot for a little on the looser side or on the tighter side? I have one that I used both the big and small shim and I can fit the gauge but it’s so tight that it leaves an indention on the upward facing shim. If I take away the smaller shim and just run the big one, it’s on the looser side.

Just figured I’d ask for some help here before I end up making the wrong decision. Thanks for any advice

So they are supposed to be 1.800" on installed height with a +/- 0.015". As long as you are in that range you are good to go. If you cannot get it there then you need to buy some different shims to get them there.
