I just replaced the valve stem seals on my 350 engine, but I dont know how to adjust the valves. Can any one help me?

 

There are several methods that achieve the same thing but I just did a yahoo search for it instead of typing for 30 mins explaining it. Here is a link but to more general internet searches and you may find better info.

What I will say is 1/2- 1 round of preload after zero lash with piston at top dead center on the compression stroke.
