A double roller will fit under the factory cover. As for brand, just about any name brand will do. I have used Melling and Cloyes many times with out any complaints.
Some kits will come with a multi-position crank gear. Straight up or 0* is always safe and reliable. Advancing will move the power lower in the rpm and retarding will raise the rpm. Not necessarily make more or less power, just when the power band begins and ends.
