A 2.2 head is completely different. Especially the exhaust ports, they need a LOT of work just to get close to a 1.9 port. Plus there are areas in the intake port that are particularly thin. Are you putting big valves in the 2.2? Porting the 2.2 head with stock valves hurts torque a lot, the low lift airflow drops dramatically.
