"FE ?-1970 or so... 352 to 428, including the infamous 427... Big block, canted valves... very good motor. HEAVY!!"
No FE had canted valves, they are in line, except the rare SOHC hemis.
"I was always told that the 302 Boss was a 302 with 351C-2V heads not 4V heads but I don't have anything in print."
The Boss 302 (in 69) had the pre cursor to the 351C 4bbl heads with slightly larger, .060, valves. The 70 head had the same exact size valves, the water passages on the heads and the valve keepers, single groove as opposed to multi groove were different( although the later Boss 351 used single groove), though can be swapped either way with some minor modification.
