spark plugs?

[keepinitril]

Im goin to throw a set of p heads with bigger valves, and then the gt40 manifold, and a small blower, were shootin for 400hp. I still need to buy a set of spark plugs, and as far as Ive seen, they all do the same thing, the only difference, is how many electrodes, the material made of, and then theres the pulstar(which cost an arm and a leg)

any thoughts, or just get the 4/each ones?

my thoughts...

1-electrode only (the 2 and 4-electrod plugs hurt by shielding air/fuel mixture from spark)
N/A = copper (stock gap or larger if aftermarker ignition)
Boosted = iridiium (around 0.030-0.035" gap)


If you have the heads off, index the plugs to face the intake valve in the direction of the incoming air swirl into the combustion chamber
