What Ole said, I checked mine this weekend on a build I've started & it sits at minus 0.019-0.020 below deck height. They vary a lot from the factory, so the only really safe way to find out is to measure TDC with a straight edge & feeler gauge or dial indicator.
If you guess at it, you can run into problems without knowing what might happen & a KABOOM will be the educational benefit (that's why education is so expensive).
