spark plug gap

does anyone know the recommended spark plug gap for an '88 K5 w/ 350? I looked in the owner's manual and found nothing.

.045" seems to work in HEI's. If it were mine, I'd gap it @ .045" in spite of what a manual may say.

It should be listed on the sticker under the hood with all the other smog info on the radiator cover.
