Streetmaster to Airgap

I believe ANY small block and big block mopar head from 1964 and up can be worked with and made to perform to a point. 302's are no exception, they can be ported and larger valves installed which will greatly improve the performance compared to stock. But some heads allow the performance to go beyond other heads, or have a much higher ceiling.

• Back to the point of the intakes (what the thread was about), I don't know of anyone that would be excited to bolt on a streetmaster and lose horsepower. And that was the topic, hp.
