Re: Valve lash on a 350!!
On my new 350 i turned them between 1/2 and 3/4 turns. When I first started it they chattered but quickly stopped. Small block chevys can be prone to cam problems, mostly 80's 305's, but anyway, I would try it again but dont turn them so far. You can do it with the engine running too, it makes a mess, but it is simple. Take off the valve cover, start the truck, back the nut off untill the rocker is chattering, then tighten it until it just quits making noise.
