As for what was called a wedge, I always thought that open chamber heads were not considered a wedge. For that matter, I would have said the 4 valve head designs, like the 4.6 modular, are not wedge engines. I thought that the head being flat over part of the piston, with the valves deeply recessed, with a ramp connecting the two areas was a wedge. In other words the ramp is the wedge. I don't have any recollection how I came to that opinion. I may have assumed it. Anyone know for a fact what the wedge refers to?

that is exactly how the term "wedge head" came about!!!!!!!!
You are right in your description,started back with the NASCAR boys to denote those engines from the "hemi" engines.....
