edelbrock heads on a 318

The Edelbrock heads work on 302's and 327's because those engines are designed to be high-po screamers that rev to 7000 RPM's. 318's are completely opposite of that; that's why they went in everything from 4-door Valiants to full-size pickup trucks. If you want your 318 to run like a 302 or 327 then by all means go ahead, it's just that we thought you might prefer a more street-friendly engine with more torque.
