I have 4v Open Chamber heads. What are some good heads to go with to get good low end power. Im looking for some nice heads. Does anyone make any aftermarket heads. Ive heard that the best heads are the 4v closed chamber or the aussie 2v closed chamber heads. I just want to know what all you cleveland gurus have to say.

You have open heads? Have you had them off the engine yet? If your engine is stock 1970 they should have closed heads.

To answer your question, it depends... do you wnat your motor to make power up high or down low? Aussies make brutal low end torque, while the 4V closed will let the engine rev to the stars.
