I looked up the casting numbers on the heads on my old 327 to verify what appears to be the "camel humps". Now, I'd like to find out more about these 'legendary' heads. What makes them so special? 160cc intake and 62cc exhaust ports, with 62cc chambers...is this good? What's the significance of these volumes?

If you can't fix it with a hammer and screwdriver, you need a bigger hammer.
