Had to resurface the block base , and afterwards i'm left with what seems to be a little high liner protrusion measuring 0.15mm on all the 4 liners (measured with liners and base cleaned and without O-ring fitted) .   Haynes says maxi liner protrusion is 0.10mm , though i also found info (as well from the Haynes) that the 0.18mm is maxi ?!? ..   Anyways , is the protrusion measured at 0.15mm considered too high or not ?   D
