port matched intake on stock 781 heads
Hello, Run a 489in chevy with unported 781 casting heads. 219/188 valves being the only Mod. Have a dart intake that I am sending in to have some work in the chamber under the carb. Would it be ok the port match the manifold. Am worried that the ports would then be bigger than the cyl head ports. Kinda like using a square port intake on it. Thanks
