The heads on USA slant 6"s did change some about that time to eliminate the spark plug tubes, which often leaked oil. They also might have received hardened valve seats to help deal with unleaded gas. But the valve arrangement stayed more or less the same, with a wedge chamber and inline valves both on the same side of the head. And the compression ratio was always fairly low, except for some 170 Hyper-packs that featured 10 to 1 c.r. for the 1960-61 NASCAR series for the new "compacts". The Valiants wiped the field with that hot rod combination--way faster than the Falcons and Corvairs, and because there was no good competition, the series ended very soon.
I have tinkered with slant 6"s for nearly 50 years and also have owned several Hemi V8"s. The hemi valve arrangement puts valves opposite or nearly opposite each other at quite an angle between them, and the spark plug near the center of the dome shaped combustion chamber. Wedge engines have valves that are inline or nearly inline and combustion chambers that are shaped like a wedge.
None of the USA produced Chrysler slant 6"s had hemi heads. Ever!

Rustic places with cheerful names like "The Griffin" "Red Lion" or "The Plough and Harrow" are found dotted around the country lanes all over the place. The warm glow of yellowish light can be seen for quite some distance at dusk, and
