Yes 14.4mm @ bind

And Supertech don't specify anything about maximum recommended valve lift.
I guess mainly because they know that you can't go even close to 14.4mm on the 4AGE head. (The wildest camshafts on the market for the 4AGE 16v are all under 12mm)

As a side note, the OEM springs are progressive while all the aftermarket (that I can think of at least) are linear.

BTW, I'm surprised you reach coil bind @ almost 26mm (1.017") with the OEM spring.
When I tested mine (on a vice) I was @ 25mm (0.985")
