oh, and stock port flow rates? NFI never got it flowed before the work started. i know a ported 5me head can do about 135cfm at 1.5 inches :nods:
or something like that anyway. hopefully 7m will shit on that.
ps, there are 2 types of 7m intake port divider, long and short. i decided to go with a short wall divider for hp potential, but i think all 4a's have the long wall.
talk to anthony at TCHS. its way better than anything i could write
