I'm a little confused on which head gaskets I should be using. I bought PRC LS6 Heads for my 02 SS, but not sure which gm gasket, #12498543 or #12498544? I bought the gasket kit and it came with #12498543. What are the differences between the two? I am just doing a h/c swap, no fly cutting or milling.

thanks
