So modified heads are the only way to make power? The engines are not sold completely blueprinted it is still a manufactured product. it's made like that so owners/engine builders can finish the engine anyway they see fit within the rules. Same thing that has been happening since the early 60's
There is no other way to improve a combo? Tuning, testing ect? Just do the heads and let it rip?
