I think the other side was 7, 7, 8 from front to back if I remember correctly.

I port matched mine when I had the heads off...
...and didn't notice a single difference in power or fuel economy (same thing Mance found if I recall correctly). Grinding for a couple hours with a cordless Dremel was fun though.

I will definately dyno before/after the heads...but what I'd really like to do...
Is return my intake to as stock as possible and do a run, and then a comparison run with all of the Mance parts installed. I know for sure it is a drastic improvement, but I'd love to have some numbers!
I wont be able to afford the IM/heads until at least summer...too many things on the list before them. ;/
