Hey all, im trying to figure out a solution to my problem. I have a 63 with a 327 in it. The heads have angled spark plugs and the car has longtube headers (unsure of the brand). The car also has an HEI ignition. The boot on the number 3 plug is touching the header and there is no way for it to not touch. What would be the best solution? I dont think a shorter plug would solve the problem either and the header tube has already been "massaged".
