Hey fellas,

Lifter preload...

My cam is different, my heads are decked and my gaskets are thinner.

Ive measured .150'' preload which is way too much. Engine wont idle properly and the valve train is a bit noisy. (Ive just done a full engine rebuild)

Ive noticed most people recommend .020''-.060'' preload. Does this seem about right?

Does this mean that if my pushrods now are 7.050'' long then to get me in the middle of the 20-60'' preload range i need 6.95'' long pushrods? Does that make sense?
