The kit came from the UK in less than a week to Australia and the bore was honed to .004 in which is perfect, the rings had to be gapped slightly but a great quality unit.

All bolted straight on to a 1972 T120V engine. Tappet blocks hammered in nice and tight, gudgeon pins were smooth and tight into the rods. Even the existing dowels fitted straight in. Great job, gold stars all round.
