That would be directed at the longtube headers. If the O2's can't stay hot enough the car will go in and out of closed/open loop. The Lt1 cars use a 4 wire sensor so I assume they are heated. I had no problems with them on my 96 SS. You might want to search some more to see if people really were having problems with longtubes and non heated sensors. You might need the heated O2's.
