The cam in my 512 is a lunati that specifies lash of .026 intake and .028 exhaust. I spoke with tech support at Lunati and they confirmed that this is hot lash. knowing how much fun it is to work on a hot engine is there a fixed amount of adjustment from the recommended lash for setting on a cold motor (aluminum head, iron block)? If not, given the time it takes to lash all the valves, the engine temp will change. Is it best to set half the valves, restart the engine to let it heat back up and then set the other half?
