Re: 356 CI Compression Ratio

I have found some iron heads from 22nd series and later -- at least three 288 heads, a 327 and a 356, plus one mystery HC head with no displacement indication. I assume HC is high compression, but oddly the combustion chamber is much deeper on this head. It also doesn't have the flat center ridge running front to back. Anybody have info on what this HC head is intended for?



Also, any way to distinguish a 327MT vs. 327AT head?
