SpeedyTTZ

Whats up everyone?....I have been told to port out my cast flashes from one my buddies from the 300zxforums..I am wanting to know more about this process and how it is done...I read the article from sport compact car on the "Project Z" and they did that process to that VG block...my question is that how do you do the process what tools are needed exactly and how much do you need to port out from the water passages?.....I saw some pics of the difference and I have admit that it looks like it will help 100 times better over stock....if anyone has any info leading to this mod please fill me in cause I am getting my motor back together in the next week or so and I want to get this done!

thanks
