Cylinder base shim needed?

I'm looking for a little help from those who know. I'm putting together a 2.0 with L pistons and cylinders. I measured the deck height today using the CE method in Wayne's book, but it seemed way to large at 2.2 mm. According to the book, it seems like the suggestion is to remove the .25mm shim to decrease the deck height and bump up the compression ratio a bit and bring it all back in line.

Is there an issue if I run without the cylinder base shims? I've built type 4's and FV race engines without the shims to get max CR, but they were also engines that would be torn down frequently. This engine will not be one of those! Will this lead to oil leaks, etc. down the line?

Of course, I have all of the barrels on without shims before I started thinking that this may not be a good thing...
