    I'd say that it's not a bad idea with that spray size to go ahead and add some Pushrods, Valve Springs, and Retainers and locks.

    No your shop may try and get the more expensive items so they make more profit on them. Do a little research and you should find them at pretty good prices.

    if you want rockers that work, then get the vinci/crane accelerated lift kit. used the 1.8 rockers on the wife's car on stock cam and picked up 17 rwhp. the kit is $669.00 through vinci. comes with rockers, posi-locks, guide plates, screw-in-studs, and shorter pushrods. i also put in the matching vinci/crane springs.
