    I have seen flanges made from aluminum that are attached with counter sunk flathead machine screws that have the wider pattern drilled in them. The headers then fit onto the attached flanges.

    valve cover designs for GT40 engines

    New motor oils are bad for Older Engines with Flat Tappet Camshaft

    Doug68: Your two examples illustrate the same scrubbing type of friction that ZDDP and Phosphate helped to overcome. They actually created a film that bonded to the metal over time. With the Auto Manufacturers requesting and the EPA (USA)dictating that they both be reduced to prevent the...
