If you are talking 205 AFRs then no. You would need valve relieves and a stock motor will NEVER EVER reach full hp potential of those heads I would go for 165s if I was you and you plan on leaving the car NA
what i want to do is a have a fully built motor, i just dont have the money for a new block i want 225 cnc heads with a good cam on a solid block and turbo my car
