LS3 heads versus LS6 heads?

799 have the smallest chamber out of the 3 pairs of heads I have now. 317s and 823 heads are about the same at 70cc. 799 are 64cc so they will bump up compression

My bad you are correct. I was thinking about the 317 truck heads. All these different casting numbers get me confused sometimes.. haha I am use to building sbf's..
