Yes, and properly done you get 15+HP - paste the link in my signature for more information. Here's the numbers...........
Stock upper intake runner size = 1.588 sqin.
(2-9/16" half circles, or 1 1/8" dia + .5"x1.185" rectangle)
Stock Lower intake opening @ head = .875" x 1.675" = 1.46 sqin.
Stock E7 Head intake runner = 1.05" x 1.90" = 1.995 sqin
Stock Lower intake port @ head = .875" x 1.675" = 1.46 sq in
Stock Lower Ported = 1.12" x 1.75" = 1.96 sqin
1.96/1.46 = 1.34 or a 34% increase in flow area.
