Weird Groove on Converter snout/bad leak

Trans shop says they are going to replace the bushing/seal. He thinks it looks like either the tranny wasn't lined up straight, or possibly wasnt snug in the crank... I have to take my motor off the stand and see if it is a good fit in the crank. There is a shop that builds converters and can replace my snout, I need to call tomorrow on pricing. Right now i only have a 2800 stall converter, I would like to go to a 3500 possibly. If that shop can change the stall/snout cheap enough i will go that route, If not what converters do you guys recommend that wont break the bank??? The one I had was a Hughes, seemed good, but like I say it has an advertised flash of 2800, but my motor is making it stall a lot sooner than id like
