An E head should be 85.5 mm thick while an F head should be 87 mm.

In D-jet heads you have a port for coolant temp sensor, which is small,
fine thread, and one for the thermal timer which is 1/4" pipe (almost 1/2",
coarse thread) as well as about a 3/4" hole for an auxiliary air valve,
with 2 1/4"-20 UNC bolt holes to hold it in. Which of these holes does your
head not have?

I've not studied the 74 and 75 B20 heads closely, but some of these holes
are not used on the CIS injection system.
