Re: Building it correctly - getting the crud out

Some old crud which may come loose in the rocker shafts is not the same thing as ditto in the main oil feeds.

Then again, one should not clean and overhaul one of our Packard engines the same as an in-&-out overhaul shop.

As an aside FWIW, Pontiac had the right design with their ball-stud rocker arms in 1955, which Chevrolet copied BTW. No cleaning issues with that once they got rid of the rocker stud oiling and went to pushrod oiling. IMO, there was no need for rocker shaft design in the Packard V-8 since the RPM was not that high.
