i have my motor just about done it is stock i just put all new gaskets,freeze plugs,timing chain,oil pump etc as i had to pull it out to some rust fixed. the only thing i am not real clear on is the stock rockers some people say just torque to spec but don't i have to wait for one valve to start close and the other open then torque one and then rotate till the other starts to open to do it? thanks for all the help guys
