i understand that i can use my stock valvetrain, but would the portflow valvesprings be a good setup or would they be too stiff for the s2s1 cams? or would it be better to just go with itr valvesprings. or maybe portflow inner/ itr outer combo? oh yea this would be all on a b18c1. thanks

 

portflow are very good valve springs, and would work well with the skunk stage 1's. itr's would also be good too! Something to think about though, if you ever want to upgrade cams later on, the itr valvetrain, will probably not be sufficient for the higher lift cams you upgrade too.
