I thought the big valve upgrade referred to swapping the head from the
newer 2.3 liter NF engine (130 hp), which came on the 5K/100 starting in
mid 1987.  I think one of the main reasons for it's higher HP is the larger
exhaust valves, and it's supposed to be a simple swap/upgrade.  I'm not
aware of any trade-off re: loss of low-end power, etc.
