Bud,
Logic says the double-row chain should last longer but one has to remember
that the factory would not have made the change to a single-row chain if
they expected it to fail within a noticeably shorter period. I'd say that,
with your mechanical skills and the ease of removing the timing cover on a
late B, the cost of a t/cover gasket and a new single row chain at - maybe -
75K miles after the present rebuild would be a better expenditure than a
pair of new gears and a double-row chain at this time.
