Valve Lash Adjustment

I spoke with the engine builder and he said it would be a one in a million to have a roller cam go bad in the first 1500miles. He suggests a push rod issue if there is any at all. I am going to adjust these with 0 lash plus 1/2 turn of preload and see what kind of result I get. I will inspect the pushrods for any obvious wear or bends. If anyone has a tip for inspecting the pushrods while in the engine let me know. I would prefer not to pull the rocker assemlby off unless absolutley necessary.
