My books list the AC 44FF as the standard plug for 1965 Corvairs with the
110 and 140 hp engines, The AC 44F is 14 mm dia and 1/2" reach with 3/8
thread length. The AC 44FF is a full thread type with all 1/2" reach
threaded and the AC 44FFS is full threaded 14 mm with extended tip.
Personally I prefer the NGK BR6HS.
