So I am rebuilding my engine and bought Chromoly pushrods from Raby. I have read that you set the valve clearance to 0.000 instead of the .006 that you would with an alumium rod. I am just wondering what are the physics behind that difference? It just seems that as things expand I would end up cooking valves. Hoping someone much smarter than me (not hard to do) can explain the reasoning behind this.
