Re: LS1 Step headers speaking of losing low-end TQ so to speak with these stepped headers. Is this just becuase of the diameter of the primaries?
my understanding and jmX's testing the MACs have less TQ all over than say the FLP/standard Dynatech headers which are longer but same diameter primaries
so is 1 7/8ths really that MUCH of a difference over 1 3/4 to kill low end TQ? I would venture to say not. They may suck on a stock cam? but on a typical 221 and up duration cam I think it should be ok.
Maybe Madman or Jay Billingsly can chime in on this

on a drag racing engine like yours i think it would really help imo but i'm no exhaust guru.
but since you have a stock cube motor, the 1 7/8 primaries would hurt you down low, but you have to remember that an engine is just a big air pump, so opening up the primaries down the header will help with power, the question is HOW MUCH?
personally, it would work well on your motor but i think it would work better on stroker motors or anything up in the inch catagory for people who still want more torque down low
