Matt those specs (and that link) are for gdb rev D and E jdm sti's. That is, version 8-9.
Graeme's engine was a version 10 dual avcs. These started in 2009 (grb rev A).
There is no chance the cams are the same for the gdb to yours. Reasons are:
1. Dual avcs started on ej207's with grb - different cam profile required
2. Version 8-9 jdm sti's (base model and spec c) all shared the same cam profiles as the earlier Version 7 Spec C RA-R. That is, at version 8, Subaru Japan went to the more aggressive, exclusive spec c cam profile for even their base jdm Sti offerings.
3. Head castings version 8-9 jdm sti's were identical to the version 7 spec c and Ra-r heads. The difference is the version 7 RA-R heads had hand finishing on the port bowels by STI. This practice stopped after the v7 Ra-r.
You can measure the cam lobes from base circle to tip, then deduct the base circle diameter (using the same thickness as the bottom base of the lobe all the way around). This will give you your cam lift.
