What is the difference? Between
Edelbrock - Headers
1998-02 Camaro/Firebird with 5.7L LS1, slip-on merge collector
(1-3/4", stepped to 1-7/8", 3-1/2" collector, mild steel)
and
Edelbrock - Headers
2000-02 Camaro/Firebird with LS1, fully welded
(1-3/4", stepped to 1-7/8", 3-1/2" collector, mild steel)
they both seem like they can go with my firehawk

the difference is one of them they have already welded the collector for you, and the other one you can tune your exhaust and weld the collector where you want it
"Headers with slip-on merge collector feature an expansion cone on the exit of the collector. The slip-on design allows for tuning the primary tube lengths to individual engine requirements"

Go with the welded collectors, I think a slip joint will leak before a welded slip joint will leak. 
Tuning will help get the most out of your money, and take care of SES lights. Check out the AIR/EGR/Rear O2 sticky.
