hey guys i have a question:
i am puting gt40p heads on my car with the b303 cam with 1.73 cobra rockers, what valve springs do i need to put on my heads??
thanks
It is suggested that you have 130 seat and 320-330 open!! you will need to change the rotaters on the stock heads as well!! And as said above... give me an email, and let me se what I can do with the drop in / no machining spring kits!! cool??
