Since I have all the tools necessary (Die Grinder, Air Compressor, Bits, etc) I was looking at porting my front manifold since it would basically be free. I have heard that it is poorly casted from factory and doesn't match the head ports very well. Truth on that? I have yet to remove my manifold and check this. Has anyone ever done this? What all would I want to do with it while off the car? I was thinking just a basic port match/gasket match, whatever you want to call it. Also does anyone know if our factory gaskets are re-useable? Thanks.
