I just chatted with a friend that is a expert about turbos. He simply explained if you trying to keep it in the stock rpm range, don't port the heads, If you are going for maximum horsepower/rpm then they need to be ported.
To me, forced induction is just another system to maintain. It is a means to add air flow to make more power. I know that is a huge simplification, but that is how I look at it. I love all classic Mopar engines from the 170 /6 to a 440. From the 50's to the 70's. If someone wanted to hot rod anything, I was up for it when I was younger. I've even seriously souped up a Ford 170 special for an early 60's Falcon and loved the end product. I'm just not interested in an extra system. Any classic Mopar engine can be made to perform well enough for me. I love driving "A" Bodies cross country, all day long, my whole life. Mostly with 273's. That is what Mopars excel at.
