Re: need help quick with lg header issue (RyneZ06)
I wouldn't.
Get a new set of GM LS1 exhaust gaskets.
If your pressed for time; use the ones that came with the headers but, be prepared to replace them if/when they begin to leak.

i wouldn't.when i did mine,the dealer sent me the wrong gaskets,so i used the ones that came with the headers[i was in a pinch],i used locking header bolts and tightened them up evenly,so far so good,no leaks[2000 miles since install].

Re: need help quick with lg header issue (RyneZ06)
Depends on how many miles you have on the car. I would use the stock GM gaskets over the cheap Borla gaskets provided with the headers. I reused mine on my '04 with no problems. However, if you have several thousand miles on the vette, then you may want to purchase a new set of OEM gaskets.

Re: need help quick with lg header issue (wrustywrench)
Lou recomends oem gaskets and the LS1s at that not the LS6 gaskets as the exhaust port is a diffenent shape and the LS1s fit the header better, the supplied gaskets are junk as stated earlier.
