well, if thats the case, then you need to be on top of them anyways. you prob have trick valves, and retainers. at which point, a little more noise is to be expected.
what parts are in there may i ask? ferrea? supertech? plz update us on this. and check and set your valves asap. taking a close look at every piece in there, 10k rpm is sweet, but you have to stay on top of these parts. if you expect them to live.
talk soon. dave

Yeah a little noise is to be expected and that is fine but they are ferrea. Also with titainium retainers and dual spring set up but no worries my tuner just came up from greensboro and adjusted them and re-tuned the ems. Hardly any noise and runs great and now i am back up at 11,500 rpm with no prob. Before we adjusted them we checked them and the intake was at 0.016 and the exhaust was at 0.012 and in which is very loose i know. but like i said they are tight and the car is running better than ever. thanks for all the info and help.

best of luck to you with the ferrea's they are known to frisbey. stupid ferrea doesnt make an s2000 specific setup. they use all the same diameter springs, and then RE part # them. lame. so the vtec rocker hits the retainers, and will cause them to come off. the springs need to be smaller diameter, and the retainers need to have an arc thats sharper, with smaller diameter. supertech is the only setup i know that is as reliable as stock.
