Switching 241 heads to 5.3's. Headers?

Hello

Just wondering when I switch my heads on my stock ls1 to the 2.5 5.3 (706) heads if I can keep my headers I currently have? Also what header gaskets should I purchase?

thank you.

All the LS heads have the same exhaust ports, so your current headers are fine. Get some GM multi layer steel (MLS) exhaust manifold gaskets. Use hi-temp copper anti-seize on the header bolts too.

Great news. Thanks for the anti seize tip as well!
