Good deal. Still seems like a lot of work extra work to put them in though. A cordless drill with a right angle head and you should be golden. But whatever you think is best. Be sure to tape something thick and soft to the deck of the head so you don't nick or gouge it or just be really careful with it. Don't want to put it back on only to find a leaking head later. Also, if you're not already thinking about it...go ahead and coil the remaining cam cover bolt holes while you're at it. No sense in going back in later for another one getting stripped out.
