Hi, have a question about the 1090 intake.

Is the 1090 intake made so that one carb feeds 4 cylinders and the other carb feeds the other 4? Or does one port feeds 2 of the cylinder? Or does both carb feed all eight?  My problem is that cyl 1,4,6,7 looks like it running to rich. Sparkplugs is black and the other 4 looks fine.  (Mallory unilite dist. Isky3/4 cam , offy heads, merc cranc, fenton headers. Ebu carbs)

If its so that one port feeds 2 cyl. Wich port feeds wich cylinder?
