    My understanding is that the 799 head is the same head as the LS6 243 head. If I remember the history correctly, the 243 was the initial head for the LS6 and made in Canada. The 799 head is possibly made in Mexico and used on 2007 and later LS2s?????.

    Thanks for your help. Do you know if the 799 casting can be a direct replacement for a 241 casting head?

    I do not have 1st hand experience with this but.....

    Several of the last made F bodies came equipped with the LS6 block (including my 2002 SS) and the LS1 241 heads. The 2002, perhaps the 2001 F Bodies also came with the LS6 intake. My logical thought would be that the 243/799 heads would be a bolt on to the LS1 block.

    Perhaps others with experience with the 243 or 799 heads can verify that a 799 head is a direct replacement for the 241 head. If so, my understanding is that the 243/799 heads flow quite a bit better than the 241.

    If the 799 head is the same as the 243 head, then yes they will work on a ls1

    Thanks for all the info. Hopefully I can install the 799 heads this weekend.
