Well I have to change the intake gaskets both upper and lower. But I do have a question... If the gaskets are paper how do you not get some of left over gasket from going into the intake port? I mean I started to peel one side and its so brittle. I almost have to resort to a razer and scrap it off. But I will say that the intake ports are huge. Just by the naked eye it would seem that they have more volume than my 231cfm dual port 4v head. -Mark
