ok today i went to a local tuner shop to get a quote on how much it will cost to install my itr cams, itr dual valve springs and itr retainers. what the guy quoted me was $350 and to me that seems high. anyone here ever paid anyone to install their valvetrian and for how much or how much should i be paying for them to install it? i know it's pretty straight forward but i just dont got the tools and if i had someone who can guide me through it im pretty sure i can do it but i rather get it professionally installed.
