I've been reading all these post, great info guys!! I'm currently installing Heddman 4 tube headers in my 68 MT 455 with E heads. I have the pass side done and gonna install the drivers side next. My Question is their a tork spec in these aluminum heads? AND Has anyone have header leak problems at the gasket? Are the header bolt loosen up after driven the car? Thanks Steve
