Re: Retighten Cylinder Head - Service
I highly doubt that most engines get a retorque on their head studs. I have done it on a few performance engines immediately after their first hard run but that is it, never on anything else. You are correct that to do a retorque, they need to be loosed a bit before being tightened. If they were properly lubricated from the factory, breaking them free and then going to torque should be adequate but you can certainly put on more never seize or whatever your preferred lubricant is. Personally, I wouldn't bother to do this unless I knew that these engines had a habit of blowing the head gasket but it is your engine.
You never need to see timing marks or use a timing pin to do valves, you can watch them as it sounds like you did on your old car.
