Preheat oven to 350F. Place garlic on piece of foil; drizzle with olive oil. Enclose garlic in foil. Bake until garlic is very soft, about 1 hour. Cool. Squeeze garlic cloves out from papery skins into medium bowl; mash garlic with fork. Mix in butter, cheese and parsley. Season with salt and pepper.
Transfer Gorgonzola butter to sheet of plastic wrap. Using plastic wrap as aid, form butter into 1.25 inch diameter log, wrapping plastic tightly around butter. Chill until firm. (Can be made 2 days ahead; keep chilled). Cut into 0.5 inch-thick rounds.
For Onion RingsPour buttermilk into large bowl. Add onion rings; toss to coat. Let stand 1 hour, tossing occasionally. Mix flour, onion powder, garlic powder, salt and pepper in another large bowl.
Preheat oven to 350F. Pour enough oil into heavy large skillet to reach depth of 3 inches. Heat oven medium-high heat to 350F. Working with a few onion rings at a time, shake off excess buttermilk, then turn onion rings in flour mixture to coat. Fry onion rings until deep golden brown, adjusting heat as necessary for each batch to maintain temperature at 350F; about 2 minutes. Transfer onion rings to paper towels to drain, then place on baking sheet and keep warm in oven while frying remaining onion rings.
For SteaksBrush steaks with olive oil; sprinkle with salt and pepper. Heat 2 large non-stick skillets over medium-high heat. Add 2 steaks to each skillet and cook to desired doneness, about 5-6 minutes per side for medium-rare. Serve with Gorgonzola butter and onion rings.
