Well I put the supercharger on about a month ago and now for someone unknown reason maybe extra airflow the driverside BBK long-tube header gasket is leaking and the car sounds like crap. I was quoted $550 just in labor to change out the gaskets. I did some research and see that a lot of people us the Ford Racing metal gaskets but the guy here said either carbon or a fiber gasket would work better since there wouldn't be any warping or detoriation of the gasket. I know the Ford Racing gasket runs about $96. Does anyone have any input/knowledge on this carbon/fiber gasket and if so where to purchase it. I want to get the best one since I don't want to go through this again. Way too much trouble and money for a simply gasket.
