Lol I read the numbers wrong out my book. Says anything more than .039 is needed resurfaced. So I went off the bottom number of my feel gauge cause no way could it be going off the top number.
What book are you referencing? Where do you live? Only reason I am asking is that I agree with RatRod that .039" is WAY to big of a spec for flatness of a head or block face. Out of curiosity, I converted .039 millimeters to inches and it comes out to .00154", which as RatRod suggested would be a more reasonable number to be a spec for flatness.
Is it possible your book is giving you specifications converted to the metric system, and is calling out the flatness spec as .039mm (Millimeters)?
