6.0L LS Head Test-Who Wins-799 vs 823?
I compared a set of stock 799/243 cathedral-port heads vs the 823 LY6 rec-port heads on an LY6 short lbock. The motor was equipped with a healthy Comp cam and run with the Dorman LS2 intake on the 799 heads and stock LS3 intake on the LY6 heads. Both heads had 26918 springs.
