1 3/4 headers are more than enough for any motor under 434CI. Collector size at 3" works find, with about 12-15" length.
IF your under 383" I would run a 1 5/8 header without worries.
Ran them on a 406, lended mine 1 3/4" to corky and he only gained .05 on a pretty hefty 406 motor. Not much to write home about.
