its hard to tell about the front tensioner location cos its hidden behind the timing belt cover, but no not all VL motors are series 2 i think 87 on are, but R31 motors are im fairly sure, u will have to look on the exhaust side for the bungs in the block, the oil return drain is a half inch drive plug, and the other two feeds are just blocked off by little bolt/plugs,
but yes ur description of the two are correct,
Bubba will im sure provide more info
