tomamrow when i go to put on my 65mm t/b i want to port the opening to the mani to 65mm because i've switched t/bs like 4 times and i'm scared i'm gunna strip the holes in the mani so i want to just get this all right once. someone told me how to port it but he said it can be done without removel of the intake mani. So how can i port the opening without all the dust and crap the dremel is going to make going into the mani?
