thank you for showing me that thread. I'm assuming they gap of .028 and .030 they were mentioning is for a R model car with the blower? i have a naturally aspirated car and just want the best gap possible . is it okay to run a gap that low on my NA car? thank you kindly for all help, I'm just trying to get this 18,000 s351 tuned and up do date.

The emissions sticker under the hood of a 1995 S351 says to gap at .042"-.045" (the decal also gives firing order, etc)

Do you still have your decal?
