Default Portflow/ITR valvespring combo

Si intake springs are the same as ITR exhaust springs right? Then along with the 16 Portflow inner springs, can I use 8 ITR outter intake springs on the intake side, with 8 Si outter intake springs on the exhaust side? Or would I have to use 16 ITR outter intake springs? Thanks.

yesh, the springs are the same as the ITR but its on the INTAKE side not the EXHAUST....
before you get the portflow(plan) think about what cams you gonna run... if the springs are too stiff and the cams or not wild enough you might not get all the power....
