Place oven rack in the center of the oven and preheat to 275ºF. Pat steaks dry with paper towels. Cut each steak in half vertically to create four (8 ounce) steaks. Season steaks liberally with salt and pepper. Place the steaks on a wire rack set in a rimmed baking sheet; transfer steaks to oven. Cook until an instant read thermometer inserted in the center of the steaks registers 90ºF to 95ºF for rare to medium-rare, about 20-25 minutes, or 100ºF to 105ºF for medium, about 25-30 minutes.

In a large cast iron skillet, heat the oil over high heat until smoking. Place the steaks in the skillet and sear until browned and crusty, about 1 1/2 to 2 minutes, lifting steaks halfway through to redistribute the fat. Using tongs, turn steaks and cook until well browned on the second side, 2 to 2 1/2 minutes.  Transfer steaks to a wire rack and reduce the heat to medium. Using tongs, hold 2 steaks together and return to skillet to sear on all sides until browned, about 1 1/2 minutes total. Repeat with remaining 2 steaks. Transfer steaks to a plate. Rub each side of the steak with the cut side of the garlic clove. Cover loosely with a sheet of aluminum foil and let rest for 10 minutes before serving.

Prepare a charcoal grill for high heat with a cool area on the side; oil grates well. Rub both sides of the steak with the oil. Place the steaks on the grill, close the lid, and sear until browned and crusty, about 1 1/2 to 2 minutes. Using tongs, turn steaks and cook until well browned on the second side, 2 to 2 1/2 minutes, jockey steaks as needed to prevent flare-ups. Transfer steaks to a plate and lower the charcoal for a medium heat. (If you are unable to lower the temperature by changing the charcoal rack position, use the outer edge of the fire for the cooking area) Using tongs, hold 2 steaks together and return to grill to sear on all sides until browned, about 1 1/2 minutes total. Repeat with remaining 2 steaks. Transfer steaks to a plate. Rub each side of the steak with the cut side of the garlic clove.
