LS6 heads/LS1 headers, which gasket?

I've recently put LS6 D-port style heads on my car, and still have the LS1 oval port Long tubes. I put a set of Fel-Pro LS1 header gaskets on it but I am still getting little leaks. Anyone run across a fix for this? I know I'm not the first one to have this combo.

Thanks,
Jeff

You could re-use the old ones, but why take the chance? Buy new, that way you know they are going to seal, and keep sealing for years to come.

Yeah, I've got to change them soon. I just changed plugs two days ago and 5 of the 8 plugs were covered in soot from the leaky header seal. Before I put the LS6 heads on the car, those headers sealed up tighter than dicks hatband. Now they are sealing like
