I'm running those cams on stock springs, OEM cam gears. Looking to grab Tomei cam gears down the road but I have had no issue running them in stock alignment. Will see down the road if the adjustable cam gears and degreeing really make a massive difference. I'm sure I'll see something; Ended up w/ 10 mils taken off between the deck and head for flatness when I rebuilt the motor along w/ a 1.0mm headgasket, so they're in a more advanced position from that.

Don't feel my powerband really suffers. Just about anything would be an improvement over the OEM S14 cams though.
