be open to advice. just because you run this port like this, doesn't make it right. Brian (BDC Motorsports) also learned the hard way. He ran similar ports to you. why do you think Mazda runs a 2mm bevel on the factory exhaust port on rotor housings? plain and simple to protect the apex seal when the apex seal is closing the exhaust port. I wrote a thread at nopistons with pictures about this. So relax open your ears and learn.. we never stop learning..
