6.1 cam swap. Big deal?

My SRT Max Plus (in a 5.7) works just fine on the street. I tightened the LSA up on mine more to 108 because I wanted the choppy idle, but it hasn't given me any problems. I also run a stick, so it's less of an issue. Autos don't get along with them quite as well without some fairly high stall converters as I understand.
