Which way do the crush washers go on Delco spark plugs for '86 alum heads?
There is a washer that comes with the plug that is larger in diameter on one side. Is there a certain direction it should go? On the old plug, it is the same diameter once the washer gets "crushed". Anyone know?

Mine didn't. They are all loose in the boxes. Oh well, if it were that important I guess they would either put them on or provide instructions. I think I'll put the smaller side against the cylinder head.
