I like at the end how it talks about how "lofting the valve" is bad. If it weren't for lofting the valve, most NHRA stock eliminator guys wouldn't be competitive.

Brent,

Do you think that he is referring to potential damage to the valve train via valve loft, or potential power loss? If his complaint is due to potential damage to the valve train, that does on the short term provide an increase in power, I can see why NHRA racers would go with that trade off. The engine is rebuilt more often and the damaged parts are then replaced, as opposed to a street performance car in which the person hopes to not have to build the engine.
