I was talking with my drag race and clutching xpert and we got on the subject of porting.  I told him about this do it your self kit from race logic. My friend told me that once you start grinding and cutting the ports you will have to re niskil the cylinders. He said that the nicasil laps into all the ports just a little to protect the aluminum edge from chaffing and wear. If you were to do it your self port you would have to re nicasil the jugs at $220 each canadian or you will have problems down the road. so porting even done by yourself doesnt pay because you can do other mods that will give you big HP numbers for the same if not less money. I dont know why I posted this I just thought I would share my new knowledge.
