anything by crower=good. not exactly sure what size you need, but unless youre tricking out an oldschool trashy 8valve engine, youre going to need 16 valves. not 8. what car/engine are we talking about? and what are your plans, first of all? valves arent really goin to give you much power, they just allow you to rev higher without them 'floating'. if youre doin headwork you should go ahead and get springs/retainers/cam(cams, if applicable) to get a good combo.

if youre just replacing valves cause theyre fucked up just go OEM.

Rev higher, faster/smoother due to nitride coating, stronger to avoid bending in high hp situations and if they are larger you will be able to take in and out more air, but that's for aftermarket cams.

Why do you want to change your valves?

normal DOHC VTEC valves are already pretty big...unless you plan on bumping up the compression significantly and putting some aggressive cams in or going forced induction then OEM size is best for you.

OEM valves are just fine also.....otherwise maybe go with Type R valves.

my plan make a stroker engine kit

 

[gurusan]

I don't mean to judge your decisions or anything but a stroker kit on a b16 isn't exactly practical.

It's expensive and there's not much of a point at all since you can just buy a b18 block or something.

 

[ismael-robert]

If you do go with a stroker and you have a builder you are working with then I would ask the builder/developer of stroker of what works best with what your goals are.
