I will definitly look into that, I will also get some better photos. That port significatly changed since that picture was taken. You can kind of tell by the later pictures, but I will get one and see what you guys think.
Let me know if there is any thing else I should change or should clarify.
Not bad for some 20yr old kid playing around in his shop I guess,

Not bad at all.

I have noticed one major thing I will change in my next ports. Currently, the closing edge of the port curves upwards. I have noticed on ito's and BDC's ports that its more of a "harsh" slope at the bottom, directing the air flow, and then a small bevil to maintain the sideseal on larger ports.
I will try not going so large, but rather practicing this harsher "skateboard ramp" effect at 88integra (fluidynamics) has mentioned in the porting thread.
I noticed when blowing out everything with my air compressor, the metal filings allowed me to see the flow of air created by the ports and I am rather happy with how it looks. The air flows very directionaly, following both the opening and closing sides very well. (If that makes sense).
I may throw together a crap engine with all these extra parts and pratice ports to see how they compair to my next ones. Gotta love having 2 13bt motots laying around....

Hey Spyder, there's two tricks you can do to get a feel for how the air is churning through the intake ports -> cigarette smoke blown in to the tunnel as well as high pressure water from a hose. This will give you some good ideas as to what works and what doesn't. It's intuitive of you to use the iron dust particles being blown out as a way of seeing how it all moves but unfortunately it only lasts for a split-second.

I have several lengths of 2" flex hose to route it right into the intakes on the iron sides. Little bit of ducktape and I should be set
