What year and model STi where these out of? USDM STi cams are the same duration as USDM WRX cams ('04 at least)
Correct up to 07. (08 STI is different)

Not in the 04-07 range.

Correct:

04 WRX Cam Lift
Intake 9.25
Exhaust 9.15

04 STI Cam Lift
Intake 9.55
Exhaust 9.75

STI Cams have a bit more lift, especially in the exhaust side.
