Fair enough.........I'm in the process of starting a pump gas 540, so just like to see if these would fill the bill or if I'd be wiser going to a larger head.
Just depends what you're trying to do with the engine. If you want 700 hp on pump gas the Trick Flows will do that for you. Peak power might be in the 6500 rpm range which works good for a street engine but could be a little low for a drag race only setup.
