ok,,you'll need upgraded springs for sure. You might as well get the whole spring and retainer kit,i think it's about ~$300 from portflow.

To answer your original question,yes these springs are better then stock when using such cams.

portflows inner and the itr outer spring is good for 10,000 rpm with a max lift of 14mm, which is badass for just an inner upgrade, and interference retainers.
