ok, clifford offers manifolds, headers, cams, etc. and they are the only
company that i could find that actually lists a scout application.  i
would imagine that any 258 headers would work though.  the clifford design
are tow piece so your exhaust would need some work.  as far as intake 
manifolds go i was talking to jeff ismail of ih only and his brother runs
a 258 in his scout with a two barrel intake, headers, mild cam, etc. and
gets upwards of 18 miles to the gallon with a lot more power over stock.
back to the headers, i have had mine for 3 years now without any
significant problems except the collector gaskets blowing out now and
again and this usually occurs after a break the drivers side motor mount
when i am wheelin hard.  hope this helps ya out.  good luck
