IF you're going to replace the oil pan.. this would be the time to upgrade to the Milodon road race/touring pan... its a great design and offers superior oil control under acceleration, deceleration and cornering.... a little expensive but a very high-quality design and well worth every $$. Or else, add some welded-in horozontal plates around the sump (~1"-1.5" wide) with an angle cut for the pickup tube clearance, and a small hole (~3/4") for the dipstick... that's all I've done .. about 35+ yrs ago... absolutely the single best engine-saving mod I've ever done.... too bad MaMopar didn't design these horizontal plates into the factory pan for small blocks (BB six-pack/hemi pans have front/rear horizontal plates as factory to control acceleration and deceleration oil slosh.. helping to keep the oil within range of the pickup at the bottom of the sump). IF you use any adhesive for the side rail gaskets, sparingly apply it so the gasket adheres to the pan rails, not the block rails (easier removal and clean-up if ever needed in the future... to clean the pan instead of the block.
