799 are equivalent of 243, no major diff. except that the chamber is supposed to be "rougher" i have seen no such diff. in the chamber
all 243 heads come with the conventional steel valves,only 243 equipped on 02-04 z06 corvette and some of the cts-v came with lightweight valves.
no ls2 or any other vehicle equipped with 243 cathedral port has come equipped with lightweight valves since.
