That has to be the most comforting comment here in this thread, along with replicaracer43's.
I don't intend to run anything larger than a 600cfm Carter AFB/Edelbrock or a Summit M2008, and I'd like to run the '92/93 stock manifolds into a 2" or - at max - a 2.25" exhaust. Nothing earthshattering - I wound up with a pair of Flowmaster 2.5" exit pipes in this deal, and they are just too overwhelming for a stock look - even with turndowns.
All I want is something streetable with a bit more efficiency and internal reliability - which somewhat negates going through the trouble of doing an engine swap for yet another choked-up '60s 318.
