    I am not really familiar with checking preload. Why is it required, what does it tell you, and what does it do, rather than just torqueing to spec. ( I torqued everything and triple checked it).

    Go over to ls1tech and do a search. There are alot of threads on preload. The preload will be changed by different length pushrods. You will need to use a pushrod checker to get the proper preload.
