What are your plans this would help us all give you a suggestion? If your trying to rev higher on a N/A build i'd go with the dished valve heads lighter... Don't forget to upgrade your springs, retainers when you do this also it's not a bad idea to replace all your keepers while you've got the head off doing all this labor. Just my 0.2 cents

not going to performance, but need some stronger valves and springs but standard size for the f20, to withstand the pressure at high rev. Not planning to port it now, maybe in the future.
considering supertech's stock valves, but springs, dont knwo where to go.

Well to tell you the truth it's probably not worth spending all the extra money if your planning on staying stock internally and N/A. In this situation just go with OEM.

i think that too, but got a few techs behind me have the slight thought of upgrading it just so it can withstand the high rev and heat. They are asking me to consider it, so i decided to let my fellow s2kers to make that determination.

A stock S2000 can rev up to 9,000 on a daily basis. The OEM valvetrain is made to withstand these kinds of speed. Even an AP2 can be revved up to 8,500 with no problem. If you dont plan on revving past 9,000 (pointless if your stock) then you should just stick with stock ones.
