Also, that cam looks very dry now that its sat for years & been turned over a bunch of time... be sure to apply some cam lube all over the cam/lifters before sealing it up, then oil prime it before starting & use a good cam break in additive.

Using a ZDDP additive in with your high detergent oil for break in is not a good idea. If the cam was going to fail the damage is already happening within the first 1 or 2 minutes after start up and the additive may be still laying in the bottom of the oil pan. 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.
