I'm trying to find a place to purchase some 100 octane racing fuel in the Adrian, Ann Arbor, Ypsilanti, Milan Michigan areas. Any help would be appreciated. Thx, 65'
The 2.02/1.60 X heads should flow slightly better than 1.88/1.60 valve size. I believe there both 915 head castings. Combined with some headers you should notice a difference. 65'
