Your correct, we need to start a new thread on porting and polishing. That would help so many people on here. Not everyone can afford a $1500.00 professional full port job! Here is what I came up with and it is a fact. I remember when it took a lot of thought to do something but now it takes a ton of cash that poor class and some middle class that they don't have. yes I'm in the poor classification and that's why I study my butt off to get where I am now. Tell you what, I'll start a new thread on ported cylinder heads and its open to all cylinder heads that included other makes and models. just tell me where you want it at? Gary.
