You really don't need to keep researching this. The Autolite APP764 works great and has been tested over time by many here at CEG. There is really no need to keep looking.
The factory fine wire plug works OK, but a double plat will work better. The XP104 Autolite may turn out to be good, and I may try it next time if the price come down.
About price, I think it was the Kragen ad last Sunday that had a sizable discount and brought the Autolite double plats down to IIRC $2.99 a plug. That should seal the deal.
