I am building my head and i am wondering what valve system i should go with?
I was personaly gonna go with BC is this a good idea or no? Also i herd that the stock oil jets have a bad flow when they are under boost? If anyone can tell me if this is true and should i change them to better ones?

 

There are many competent valvetrain companies... I've had good success with supertech.

Yes, you will want to upgrade your MY2000 S2000 oil jets if you plan to boost. In fact, I would recommend upgrading them even if you don't plan to go boost.

 

ok
how do you like your supertech valve system?
i herd that the oil jets were a recall item? You know if that is true.

 

North American oil-jet bolts were changed half-way through 2002. They were upgraded to the European higher-flow design. The bad rep may apply to the earlier version.
