Not sure about the miles, it was built 1.5 years ago. Stock 2mm seals and springs. The motor has taken 100 + runs on the dyno, lots of outings to the 1/4 mile track and plenty of street driving.

Factory ports have a ventury to increase air flow and low rpm torque. Is good to port some of this ventury away but still keeping a slight lip of the factory ventury to keep aiding in air speed. Overall port size needs to be increased to allow more cfm to flow.
is that true for all factory ports, old and new? those that you showed on page 1 are REW ports, no? i just wanted to know if the old 12A ports had that same venturi or not. i was looking at a stock housing that i have here and it didn't seem that way - at least, nowhere nearly as pronounced.

LOL 
as luck would have it, a gentleman on the "other board" happened to post some pics of a 12A port-mold he made and i saw that they have that venturi. it doesn't seem as pronounced as the 13B-REW, but it is noticeable on the mold. thanks for the response though, Ito.

oh boy first post!!!
is there a specific port that works better with carbs? or are they pretty much all the same performance wise with them
on carb you should leave a much rougfer surface in the tunnle to help fuel atmoaztion.
