Edelbrock has LT1 long tubes
1 3/4 stepped to 1 7/8 not going to flow? lol, you must not know much about edelbrock.
I have no doubt that a stepped header should flow great, just so long as they build them correctly to flow good. ya know... not have any stupid bends that aren't required that hamper flow somewhere.
in all honesty, they should be awesome headers for the guys that need a header that will allow that extra flow.

Jay, why are you getting an LT1? Has common sense kicked in?
