So I'm playin with Desktop Dyno,and have pretty much everythign figured out and dialed in except for the heads. My motor has the "peanut port" heads. Oval port. I don't know which of the availble selctions most closely match my heads. Here's apicture of the avaialbe choices- My best guess was the Canted/Oval Stock ports, Stock Valves. Am I way off base? It seems to make good torque numbers....Nice and flat from under 2k rpms to 4500. Anyways....Who's got a clue? I sure don't..
