I have started porting and polishing my 317 heads. I'm curious to see where others have opened the ports and seen better flow. I have blended the bowls and opened the exhaust port a little. I've researched all media on the web that has the word cylinder heads but I know all heads are different. So your suggestions and experiences will be appreciated.
After I get my engine back together I will do a before and after dyno and post the results.
