My roadster spends most of its life in the garage. I put fuel stabilizer in the tank, battery tender on the battery, tires fully inflated, and a car cover on it. Winter weather conditions might keep me from driving it more. If that happens, I try to run the engine up to temperature and move it in and out of the garage so the tires rotate to avoid developing a flat spot on them. I've heard some people also park on a carpet to help the tires from developing flat spots. I have found if I leave the car for several months without running it I do get a valve tap (sticky) when I start it. It takes 5 to 10 minutes of driving for that tap to go away. I would not bother putting it up on blocks.
