    Are you running phenolic blocks, or just regular gaskets? Perhaps a material difference between the two sides, if running the spacers?

    6-7 degrees is a pimple on a gnat; not enough difference to matter. Your problem is something else.

    Octane and age of the fuel you currently have in the car?
    Ultimately the question is what is the octane now?

    99? Some nice tonic there.

    Why do you think it's a peculation issue?

    Are you sure your points aren't closing up?
