itr dual valve springs & ret. vs After market???
i have an itr head wth the stock valve train which i plan on using for my 600 whp turbo build. I was wondering if the stock itr dual valve springs & ret. were good enough to rev up to 9500? if not what kind will give me the best bang for my buck? I do not want to go cheap i just dont want to go all out on these parts, If it matters, I will be running stock itr cams. thanks for any help, please post links to sites that you may recommend.

You must change your retainers as jared said, you can get crower retainers. For springs the cheapest way is to use portflow inner valve springs with your type R outers. This is good for 9500 easy. I have used this set up succesfully with toda spec B cams which have more lift and duration than the ITR that your using
