Ron, Do yourself a favor here. Only do what is needed to clean the ports to each other. I would tend to lean this way no matter what the rules people want to say. Port matching is a bit different that actual Porting. I would look at the head and the intake and decide what needs the most work within the 1" rule. Keep it very clean and dont create any large bumps in the port. then clean the other component to match. creating a big as cobra neck to fit a gasket will cost you more HP than gain you. Same goes for the exhaust. I know what the rule says but sometimes being cute with a rule will cost you more than it gets you.
