The only time you should run 0 lash is when you run steel pushrods. The expansion rate on steel pushrods is the same as the cylinders, so they don't tighten up as they get hot.
When running the stock aluminum pushrods, you need to run factory valve lash settings. It accounts for the fact that aluminum expands more than steel when heated, so when your engine running aluminum pushrods is hot, it is at 0 lash. That's why you have to set the valve when the engine is dead cold. |
