Head porting

[Ed]

I just got my head back from the machine shop. They resurfaced it and installed new hardened intake seats. Now, I want to match port the intake with the head, smooth out the transition between the valve seat and the port and do a general smoothing. I will include pictures of my progress. Here is a picture of the three angle job on the seat. I'm not really happy with the transition of the port to the seat so here goes.

Here I broke out the dremmel tool and smoothed the transition of the port with the seat.

Here I've done some work on the intake port. Removed material from around the guide and excess casting material on the port walls. After I smoothed the walls I went over it again to give it a textured feel. I did this to try and maintain a turbulant air flow which will hopefully maintain the air / fuel mixture.
