Small vs mild vs large streetport

I think that it is easier to lay a rotor and housing on the iron and figure out your port timing and adjust it to what you want. I wanted a good idle and a tame street machine, so I did not change port timing at all. The larger intake runners did hurt my low end quite a bit (but they make up for it between 7,000 and 9,000 rpm).

I agree with ReTed, there is a lot that can be done for the ports without really changing the port opening at all.

I think I posted pictures of my intended port modifications in a previous thread.

The templates are cool, but they kinda ruin the fun.
