"I'll say it again. Don't make the port bigger there's math for this right. You'll learn it and my customers know my stuffs fast and its fast for a reason, its small ports you'll never see big heads, you'll see that my modified cars and my street stock cars run these unconventional small port heads and kicking peoples butts and not big cams right, big cams don't do it."
His quote is about his street stock engines lol, nowhere is he saying in that video, don't go bigger on the port ever.
He's is talking about short track roundy round engines which of course need a small port to keep in the torque curve.
Which don't need a big cam either
