Take in a set of junk heads and practice porting. Amazing how fast it goes when you are not worried about trashin em. Too bad they're cracked. /forums/images/graemlins/frown.gif they turned out nice. All I used was a tapered carbide bit and a small flap wheel I modified so it was tapered. I wasn't able to get all the rough spots out of the runners due the length of the bits but the chambers and the short side of the runners look sweet. Not hogged out either, just blended and smoothed out. We have a digi cam for warranty work, I'll try and get some pics tomorrow of the before and after work. I thought it was pretty cool anyway, the last time I did it I spent a stupid amount of time doing it being oh so careful not to screw it up. I went into it this time knowing that if I nicked a seat or went to far it was only practice and was not out anything. If it wasn't for the crack I would run em in a heartbeat.
