From the Lays website:

Our LAY'S(r) STAX(r) chips (all flavors) are made on gluten free lines, thus all
LAY'S(r) STAX(r) products are free of gluten.

*The above products (Cheetos, Tostitos, Lay's potato chips, etc.) do not
contain gluten; however, they are produced on the same line as our products
that do contain gluten. Although the lines are washed between batches, a
slight residue may remain on the lines. Individuals who are extremely
sensitive may be affected.

If you’re sensitive to small amounts of gluten, you may experience a reaction to any of the chips besides the Stax.

From the Boars Head web page:

All Boar’s Head Brand® Meats, Cheeses and Condiments, as well as Hans Jurgen® Pickles are Gluten Free.
Of course we encourage you to always read labels, and check for any specific ingredients your doctor may want you to avoid. Always check the labels on store prepared entrees and sandwiches as they may contain gravies and sauces that contain gluten.
If you have any further questions about specific ingredients, or products other than meats, cheeses and condiments, please contact us at our Nutritional Information Line by calling 800-352-6277.

As always, do as they suggest and check the label.

From an email response:
