I appreciate all the great feedback on my question about spark plug heat range options.  It seems that if I want to incrementally go to a cooler (or hotter) plug then NGK seems be the way to go.  Champions  are unavailable in a number of heat ranges and the information on their web site is confusing.
	I’ve spent a lot of time this Spring doing unexpected work on the 6 including suspension work and fuel delivery issues.  All that is now sorted and my plan is to spend some quality cruising time this afternoon. 
	Happy Motoring.
	Bob

That's actually a source of air when you turn the engine off and could be part of the problem.  our car runs better without it.  just eliminate the branch that goes to it.  but be careful about the pipe that goes back to the gas tank.  That has to be free and clear or your engine will quit running due to fuel starvation because air is not coming in to replace the gasoline that is going out.  you can just leave the pipe that comes from the back; tie it down and leave it open.  And you won't get a gas smell in the garage.

I'm not sure I'm the one to solve the problem for you  but it just seems wrong to me that you are having this problem; I don't think it's the plugs.

My reasoning is that a bit colder plug may eliminate the hot spot source of the occasional dieseling.

Hard to find NGK BP6ES now.  BP6RES is available, but I heard the resistor plugs not good with pertronix ignition systems.  I went back to champion.
