I would say that most guys don't want to go through the hassle of tearing down the engine. Cost is high for gaskets and its a lot of work for basically no reward. Some racers don't build their own engines and do not have the mechanical ability to go through the tear down procedure. Most of us have been there and done that and have our certificates hung on the wall. Now we would just rather race and go some rounds.
