    M50 block deck height

    Anyone knows what is an actual deck height of M50 block?
    Is there height difference between M50/M52/M54?
    I'm asking cause I'm stuck building my 2.8 liter high compression storker,
    I know that the block height is 211mm but it seems to be wrong, cause
    84/2 stroke+140mm rod+28.32 compression height piston gives total height of 210.32mm. this means that the piston in TDC must be 0.68mm below the deck, but today I assembled a block with crank and put one piston with rod and it came out of the block for more then 0.5mm WTF?? can anybody explain?? block is not shaved 100%!

    anyone??
