Question for the head porting experts.

No, not only will you likely hit the water jacket, you need to increase flow and efficiency the port has to offer. Watch more of his videos, he explains alot. I have watched the porting videos several times each, even the chevy and ford videos. Each time I have picked up something new. His porting book is a good read.

Oh I'm not talking about it in the literal sense. But there are times when filling port sections with epoxy helps which leads me to the question. I read somewhere years ago, like 30, that a "D" shaped exhaust port was an attempt to do somethign similar. Maintain the shape and make it "seem" like it was straight wrt flow rather than bent.
