Also detergent oil is not recommended for break in especially for a flat tappet cam. There are companies that make a specially formulated break in oil that is non detergent and has the extra ZDDP package. Joe Gibbs Driven makes a good break in oil and there are others too. The reason detergents are not good for break in is because they tend to prevent the ZDDP from adhering to critical surfaces and tend to wash it away. It is not a new thing. Non detergent oil for break in has been around since the 50's and maybe even before that. Surprisingly many are still not aware.

Thanks Tom, I will note this for when it's time for break in.
