Your engine doesn't rev to 9k+.

Also, it's not fair to compare a $2000 valve train to a $70 set of rocker arm stoppers. Common sense says that of course the best way would be solid lash, etc., but not everyone has the money for that.

Paul Sauder broke a rocker arm in half with no rocker arm stoppers so saying your rocker arm is safer without rocker arm stoppers is not correct.
