Porting Your Own Heads

dont know yet. just got them back from the machine shop today. i will post how it works.

BlackFire, you dont need a big compressor. i used my Craftsman 5hp 25 gal, a cheap straight air die grinder(Lowe's), Dremel tool with certain bits(hard to desribe them all), and Carbide bits for your die grinder that you can get from Summit or Snap-On. it took me 8 hours to do both heads of the exhaust only. that was my first time doing this. also, gasket match the exhaust. if you look at my pics, you can see where i outlined the exhaust gasket so i would have an idea how much to take out. make sure when you are doing them, to make all of them uniform as best as you can. you dont need a flowbench. use your eyes and take a good look of what will make it flow better. do one head at a time. check out the flow characteristics of the unported head. first remove the "bump". compare it to the unported again. go back and forth and keep doing this. making them equal with each other is your goal. do it by eye, or use vernial(sp?) calipers and go from there. that is the best advice i can give you. anyone who has done this more than me or does this for a living, please be free to step in and let me know if i am doing it wrong myself.
