i got my heads back and got a fel pro gasket kit, now im  ready to put top end bac together but am woundering if there is really any advantages to using those new and supposedly better spark plugs like the bosch plugs that have 2,3,and even 4 electodes or what about those E3 sparkplugs that seem to cover all the magazine ad space?? Anyone got an idea??  

not a soul of a response????

I do not think they are worth it but some do. I was waiting to see what others might say on the matter. THe reason I do not think they help much is because though they can have more arcs, there is only so much energy in spark to begin with and forcing it across more than one gap at a time would reduce the heat energy in those sparks because of reduced current in each of them because total current is still the same and is divided among two or four gaps.  

I missed this one... I just use good ol' ac43's in the 350's. the colder plug is better in most cases  

I use the E3 plugs on a 2.8v6, 350,400,and 454.I have had no problem with them they work great!!
