clinebarger

so i did some research on the net, and i think im finding that the 799 was a pre production ls6 head, and the 243 replaced them, but im also seeing some 06 corvettes with the 799 heads as well??

Casting number 799 is also an LS2 head. Came on some late 06 and up tbss and other LS2 vehicles. These are the mexico cast heads. Little rougher finish. Same basic head and flow though.
