ITR/Porflow valve springs combo

I am thinking now of using ITR outer valve springs with Portflow inner valve springs. Is this a good combo? I can safely rev to stock redline (8k rpm) using bigger cams in the future like Toda B or Skunk2 stg 2? Thanks.

Re: ITR/Porflow valve springs combo (owen_the_soyboy)

which retainers should I use? Are the ITR and GSR retainers the same? Again, I won't be revving past 8k rpm but I would like Toda B, Jun2 or Skunk2 stg 2 cams in the future. Right now I have CTR/ITR cam using stock and original valvetrain and bottom end. 130k miles and still kickin' ***!!
