flywheel tech...

ok I need help , so i got this flywheel from Ram its right for my setup, the only thing its 164 tooth instead of the 157, and it seems everyone is using the 157 with a 10.5 inch clutch.i wanted to know whats the benifit of going with the 164 tooth flywheel? i know if i use the 164, which is 11 inch instead of 10.5 i have to use a 11 inch clutch, should i just stay with the 164 or get a 157? its going on my 331 5spd. am i going to have trouble with any other aspect of the install like the bellhousing, clearance?? or anything like that
