i know this is kinda a dead topic but, i pulled my engine out and took it apart, and it looks like if i were to zero deck this thing i'd have to take about a hundred thousanths off the block, wouldn't that make the compression go super high and force me to run super unleaded? but more importantly i noticed my camshaft has a flat lobe- just one #4 exhaust, the lobe is now about half the height of the others. does anyone know what could cause this, this cam only has 20k on it. thanks for the help matt
