Preheat oven to 400°F. Slice top 1/2-inch off each garlic bulb. Place bulbs cut-side-up on aluminum foil. Drizzle with olive oil and season with salt. Crimp foil to seal and bake for 30-40 minutes, or until garlic is soft and golden-brown. Let cool completely.
Combine mayonnaise, sour cream, lemon juice and cayenne pepper in a food processor. Squeeze roasted garlic cloves into mixture and process until smooth. Season, to taste, with more salt or cayenne pepper.
Garnish with chives and serve room temperature or chilled.
