    Plug gaps don't look bent from what I can tell.

    Car has been in storage since November in the garage. Gas tank (Full) was stabil'd at that time and battery disconnected.
    Have been able to run 3.25 pulley in spring and fall until it gets too warm and knock creeps in, then I would switch to the 3.4. Switched to 3.4 off the bat this year with the old gas I figured it was the safe route.
