Not suggesting it would apply here but I'm aware of a SD Performance build in 2010 that used the Crane 99893 springs on a set of his KRE D-ports that were the 300-305 CNC version.
They were set up at 1.780-1.790 on the intake and 1.810-1.815 on the exhaust. As a reminder, don't trust the pressure stated in catalogs at the different published installed heights. Test them at your actual varified installed height with their retainers in use on a calibrated spring checker. .

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
