 Warm it up fairly carefully, then rev the snot out of it. Change the oil circa 5-7k usually.
 
 My view is dual-row are best left. If I had single row, it would be a tricky choice.

This is my philosophy now.  Lots of relatively gentle trips up into the higher RPM.  Mine's a garage queen.  Original IMS.  57K.  2002 BS. Had her for 6 months and put about 450 miles on her so far.
