I am sure the heads that came off the 1.9 engine are 2.1 heads
there has been many conversations on this list about the different
combustion chambers shapes
I have also modified a pair of 1.9 heads so the chamber shape goes out to
the sealing surface but just once and I don't think you have those heads

mmmm.........i'm looking at some heads  I took off a 1.9, and the relief, or
pocket, for the intake valves goes right up to where the sealing metal ring
would be.
025 103 375 on those.
Looked at four    2.1 heads ..........relief or pocket for intake valve
looks the same to me.
025 103 375 C on those.

Please explain.
( I  have a plan to ultimately put soobie 2.2 heads on anyway ! and engine
management
 system   )

The 1.9 and 2.1 heads look the same at a glance and most could not tell the
difference unless they had them side by side The best way to distinguish
them is to look at the chamber the 1.9 intake valve relief does not extend
out to the edge of the cylinder sealing surface
