I don't know your engine specs so I can only offer a generic opinion. If it were my engine I wouldn't put aftermarket heads on it. My cam is a fairly mild .480+ lift cam with 10:1 compression. Aftermarket heads wouldn't be enough of an advantage to be worth it. If you have the engine built up enough to benefit from the Eddy heads go for it. If I'm in your shoes I'm fixing the head issue and taking the car to get it professionally tuned and enjoying it as-is.
