That's one of the things I did to clean out my engine that had sat for 31 years before I started it up. Plus, I wrapped a popsicle stick with paper towel and scraped as much of the sludge as I could out of the bottom of the oil pan through the drain hole. Drove it 10,000 miles after that before having it rebuilt. Ran fine.
P.S. You might want to have a look at my video on YouTube of starting that engine after 31 years. Over 700,000 have thought it entertaining so far.
