those should work, as long as you use a copper plug.
i personaly have not used any NGK's yet in my grand prix.
ive stuck with autolites and they work fine for me.
i ran the AL605's on stock pulley then went to AL104's w/ the 3.4

the MSD coils should be used for cosmetic reason only.
the stock coils are more than up to the task.
mine are still stock at 135k - no issues so far here.
