Nope.The reason your cases are bent is because a GI 1911 doesn't have this ...
The 1911 has functioned quite well over the last 100-plus years without lowered and flared ejection ports. Almost certainly a problem with the ejector or extractor. OP needs to check his ejector tip and possibly tune (or replace) his extractor (although it might be worth trying a new recoil spring as well).
Here are two Colt Series 70s that don't ding case mouths upon ejection, yet do not have lowered and flared ejection ports.
