I have put the head back on the block. What is the procedure or method for installing the rocker arms? The engine has non-adjustable rockers and hydraulic lifters. Although this is an inline 4 cylinder, I assume that most or all GM engines with this type of valve train have the same re-assembly method. I am looking for some specific directions as I don't have a manual. If there are any recommendations on engine rebuildng and/assembly books specific to GM engines like this, I would be glad to hear them. Thanks for the advice in advance.
