I could see how that would work fine kwai. The longer plugs are just to close together at the top. I pulled all the plugs out and put them in a spark plug cleaner. They look brand new, although they were really in good shape as I pulled them out. The last cylinder plug towards the firewall had a very minor buildup up of deposits on it. Everything is back together now, and I'm waiting on a new coil from Ohio. More Chinese crap I'm sure.
Hope it solves the problem though.
Just out of curiosity, what is the make and number of the shorter spark plugs. I'm using the 2344 plugs I believe.
