241 exhaust ports (pics)
241 heads,,,, i shaped all the exhaust ports (cut down the rocker boss and took out the bump). i just did some pocket porting i really didn't touched the walls or the roof of the exhaust port.... noticed the 243 heads have D shaped exhaust ports, should i do that with the 241 exhaust port? included some pics for ya'lls advice and thoughts.

last one is a file photo of an unported exhaust. i used a carbide cutter to shape and then did a bit more shaping with 80grit rollers and then very quickly hit it with 120 grit rollers to make it look decent for the pics.
