I always drop the pan and clean it before running an engine. These engines get an amazing amount of sludge over the years. I've heard horror stories about detergent oil breaking crud loose etc but not sure if they're true.

I dropped the pan in my '46 with the engine in the car... not too bad of a job. And you get to replace the pan gasket too... I hate leaks!
