guys I have a question, put sleeves in tonight and doing check for flange height. the book says flange should be between .001 and .004 above deck height with all heights being with in .002 of each other. now I depth mic cylinders 1-5 and checking between .186 to .188 in each counterbores in different places and cylinder #6 the counterbore was .190 miced the flange on the sleeves and they are all .190 so I did not put any shims under 1-5 and #6 put a .003 and started to check total on all 6. I plan to go thur them all tonight reel good but doing some rough checks looks like I will be with in the .002 for all of them but my flange height looks like it will end up being .005 with feeler gage, will being .001 over on the flange hurt anything? I plan to go with it unless someone thinks it could cause a problem as then I would have to lathe cut some back to use shims.
thanks for any input ahead of time.

You need the deck height to be within spec or the head gasket will fail prematurely if to high . If to low the sleeve will work in the bore. I also would not cut the sleeve lip.
There are tools to cut the counter bore in the block if needed. Sleeve deck height is done with the sleeve in the hole and clamped down solid to get an accurate reading. Your depth mic will get you close. If all of them are at .188-189 the last is .190 would leave you in the correct height without shims.

Set them in the bore upside down and put a 50 pound weight on the top. measure from there! Jim, outside the box.
